Neurofilament Antibodies-Check Them Out

Widely Used and Frequently Published
Our Neurofilament Antibodies are well characterized and research ready. Here is a recent publication using one of our Neurofilament Heavy Antibodies. Jennifer M. Hahn, Kelly A. Combs, Christopher M. Lloyd, Kevin L. McFarland, Steven T. Boyce, and Dorothy M. Supp. Identification of Merkel cells associated with neurons in engineered skin substitutes after grafting to full thickness wounds. PLoS One. 2019; 14(3): e0213325. Published online 2019 Mar 5. doi: 10.1371/journal.pone.0213325.
Figures: Merkel cells in grafted ESS are associated with neurons expression neurofilament heavy (NF-M) by eight weeks after grafting. Immunochemistry with antibodies against NF-H (red) and KRT20 (green) was used to localize neurons and Merkel cells, respectively, in ESS after grafting to mice. Nuclei were counterstained with DAPI (blue; B, D, F, H). Shown are cross sections of ESS at 4 weeks (A-B), 8 weeks (C-D), 12 weeks (E-F), and 14 weeks (G-H) after grafting; each row contains images of the same section. Scale bars in A is same for all images. White arrows indicate examples of NF-H-positive nerves associated with or in proximity to Merkel cells; yellow arrows indicate NF-H-positive nerves not associated with Merkel cells.

i-Fect Scores Again

Knock-down of HIF-1a Attenuates Chemo Induced Pain
i-Fect TM is one of our original products. It has enjoyed 14 years of upping transfection percentages both in-vitro and in-vivo.

Here is a new study showing successful use of i-Fect to knock down HIF-1a in-vivo-Taylor Ludman and Ohannes K. Melemedjian. (2019). Bortezomib-induced aerobic glycolysis contributes to chemotherapy-induced painful peripheral neuropathy. Molecular Pain. https://doi.org/10.1177/1744806919837429.


Figure 1. (a) Treatment of mice with bortezomib (Bor) for five days augmented HIF1A expression in L4-6 DRGs (*P ¼ 0.0412, five mice/ group) relative to the vehicle-treated group. (b) A schematic depicting the site of the intrathecal (IT) siRNA injection. The siRNA was administered between the L4 and L5 vertebrae which is around 17 mm rostral to the spinal cord (SC) section innervated by the L4-6 DRGs. (c) IT injection of siRNA (1 mg in 5 ml) that targets HIF1A (siRNA) but not control siRNA (Cont), for two consecutive days, significantly reduced the levels of HIF1A in L4-6 DRGs. (***P=0.0006, five mice/group). (d) IT siRNA did not affect HIF1A levels in L4-6 spinal cord (five mice/group). (e) After determining baseline withdrawal thresholds using von Frey filaments, male ICR mice received IP injection of vehicle or bortezomib (black arrows) and IT siRNA (blue arrows). The withdrawal thresholds were measured on days 7 to 14. IT HIF1A siRNA prevented the development of bortezomib-induced neuropathic pain. (****P less than 0.0001, five mice/group). DRG: dorsal rootganglia; HIF1A: hypoxia-inducible factor 1 alpha; IT: intrathecal; IP: intraperitoneal; siRNA: small interfering RNA.


This study is the first to demonstrate that the stabilization of HIF1A expression underpins the development of bortezomib-induced neuropathic pain. Crucially, these findings reveal that the initiation and maintenance of bortezomib-induced neuropathic pain are regulated by distinct mechanisms.

Gut Brain Axis

Helicobacter pylori Induced Anxiety and Anorexia
Our PGP9.5 was used as a Hypothalamic Neuronal Marker in this study-Hajime Suzuki, Koji Ataka, Akihiro Asakawa, Kai-Chun Cheng, Miharu Ushikai, Haruki Iwai, Takakazu Yagi, Takeshi Arai, Kinnosuke Yahiro, Katsuhiro Yamamoto, Yoshito Yokoyama, Masayasu Kojima, Toshihiko Yada, Toshiya Hirayama, Norifumi Nakamura & Akio Inui (2019). Helicobacter pylori Vacuolating Cytotoxin A Causes Anorexia and Anxiety via Hypothalamic Urocortin 1 in Mice. Scientific Reports volume 9, Article number: 6011.

Images: Ucn1- and DAPI-positive cells (yellow arrow heads), or Ucn1- and PGP9.5-positive cells (white arrow heads) in the PVN cells.

This is the first study demonstrating the anorexigenic and anxiogenic effects of VacA. The authors propose the following. VacA secreted by Hp in the stomach travels via the peripheral circulation and passes through the BBB. VacA binds to LRP1 and activates the intracellular PLC-PKC pathway, resulting in the activation of Ucn1-positive neurons, such as in the PVN of the hypothalamus. Secreted Ucn1 induces the inhibition of food intake through CRF2 receptors and anxiety through CRF1 receptors (Fig. 6). The central Ucn1-CRF receptor axis activated by VacA might be a new important pathway that contributes to the anorexigenic and anxiogenic effects of Hp infection and could be a therapeutic target for Hp-induced alterations.

Neuromics' Human Brain Pericytes Guide Axon Growth

Study Interactions Between Blood Vessels and Nerve Cells
Our GFP-Labeled Human Brian Pericytes were used by Spinal Cord Injury Researchers to evaluate the efficacy of aligned microvessels to induce and control directional axon growth from neural progenitor cells in vitro and host axons in a rat spinal cord injury model. Interstitial fluid flow aligned microvessels generated from co-cultures of cerebral-derived endothelial cells and pericytes in a three-dimensional scaffold. Paul P. Partyka, Ying Jin, Julien Bouyer, Angelica DaSilva, George A. Godsey, Robert G. Nagele, Itzhak Fischer & Peter A. Galie (2019). Harnessing neurovascular interaction to guide axon growth. Scientific Reports volume 9, Article number: 2190. https://doi.org/10.1038/s41598-019-38558-y

Axon guidance at the site of a cervical spinal cord injury in a rat model. (Ai) Schematic illustrating transplantation of scaffold into a C-4 hemisection. The injury cavity is shown prior to (ii) and immediately following (iii) transplantation. (Bi) Scaffold conditioned with flow exhibits viable GFP-labeled microvessels (green) (ii) and alignment of host axons (magenta) infiltrating the scaffold in the rostral-caudal direction (grey arrow). (C) Scaffold conditioned in static conditions showing disrupted alignment of both microvessels (ii) and host axons (iii). (D–F) Microvessel and axon plots showing alignment (D,E) and length (F). Scale bars, 1 mm (Aii,Aiii) and 50 μm (B,C). Data are presented as mean ± s.e.m. ***P < 0.001; statistical significance was calculated using Welch Two Sample t-test. White arrows denote proximity of axons with microvessels. Microvessel alignment values (n = 30), axon alignment values (n = 30), microvessel length values (n = 15), and axon length values (n = 15) are from single hydrogel samples per condition.
The authors conclude aligned microvessels have the dual benefit of providing the basis for a vascular bed within the scaffold to promote cell survival and directing the growth of regenerating axons. Future studies will evaluate the functional benefit resulting from delivery of this multifunctional treatment strategy in various models of CNS injury.

Sorting Cancer-Associated Fibroblasts (CAFs)

Featuring Our Colorectal CAFS
CAFs play a central role in the Tumor Microenvironment (TME). The TME has been identified as one of the driving factors of tumor progression and invasion. Inside this microenvironment, CAFs, a type of perpetually activated fibroblasts, have been implicated to have a strong tumor modulating effect and play a key role in areas such as drug resistance.

This makes CAFs a target for cancer therapies. The challenge is the TME is heterogeneous making it a challenge to derive homogeneously relevant populations for basic research and drug discovery. This new study uses our Colorectal CAFs to identify markers for isolating these populations. Martin Nurmik, Pit Ullmann, Fabien Rodriguez, Serge Haan, Elisabeth Letellier. In search of definitions: Cancer-associated fibroblasts and their markers. doi: 10.1002/ijc.32193.

Images: Expression of common markers in patient-derived fibroblasts. Immunofluorescent staining of primary colon cancer fibroblasts (Neuromics, #CAF05), reveals a heterogeneous expression pattern for both αSMA/ACTA2 (abcam #ab7817, 1/200) and FAP (Santa-Cruz Biotechnology #sc-65398, 1/200), while PDGFRα (abcam #ab61219, 1/200) expression in tested cells remains relatively homogenous. Nuclei of fibroblasts were stained using DAPI (DAPI Fluoromount-G® Mounting Medium). Image is representative of three independent biological experiments.Cells were imaged using a Zeiss LSM 510 Meta laser scanning confocal microscope (Carl Zeiss, Jena, Germany) with a Plan-Apochromat 63x/1.40.


The authors conclude when selecting for CAF populations using antibody-based methods such as FACS, it is essential that multiple surface markers are used in order to avoid any chance of introducing unintentional subtype bias. Other available surface markers such as PDGFRα/β work well here, as do more general fibroblast surface markers like Thy-1 cell surface antigen (CD90), provided that the cell population is also subjected to selection with negative markers,

Neuromics' Islet-1 Used to Study Avian Heart Morphology

Evolution of High-Performance Hearts

Our Islet-1 Antibody showed its versatility a comparative morphology of avian hearts.

Figure: Sinuatrial node in Mallard (a–c), chicken HH42 (d–g), Lesser redpoll (h–j), and Jackdaw (k–m). All sections are in the transverse plane. The boxed areas in the left-hand column images indicate the areas of the images of the middle and right-hand columns. (a–c) In the Mallard, a nodal structure at the base of the right leaflet of the sinuatrial valve (black arrowhead in [a]) expressed Isl1 (b, c) and had a large coronary artery (white arrowhead in [b]). Sections 271 (cranial) to 1201 (caudal) encompassed the atria and the sections shown are 691 (a), 692 (b), 762 (c). (d–g) In the chicken HH42, the sinus venosus (SV) expressed the myocardial marker cTnI and this expression was relatively weak at the base of the right leaflet of the sinuatrial valve (black arrowhead in [e]). (f–g) The base of the right leaflet of the sinuatrial valve expressed Bmp2 (red arrowheads in [f]) and Isl1 [g]). Sections 17 (cranial) to 297 (caudal) encompassed the atria and the sections shown are 80 (d-e), 78 (f ), 88 (g). The sections were from the mid-height of the atria. (h–j) In the lesser redpoll, Isl1 was expressed in the base of the right leaflet of the sinuatrial valve. There was no nodal structure but the Isl1 expressing wall was thicker than the surrounding walls and contained a large coronary artery (white arrowhead in [i]). Sections 321 (cranial) to 621 (caudal) encompassed the atria and the sections shown are 401 (h), 402 (i), 422 (j). (k–m) In the Jackdaw an Isl1 positive area was seen in the left sinus venosus myocardium (l) in which a coronary artery was visible (white arrowhead in (l). At the base of the right sinuatrial leaflet no positive Isl1 cells could be seen (m). Sections 122 (cranial) to 332 (caudal) encompassed the atria and the sections shown are 190 (k) and 191 (l–m). Ao = aorta; LA = left atrium; PA = pulmonary artery; RA = right atrium; SAJ = sinuatrial junction. In the picro-sirius red images blood has been painted over with white for clarity.

Markers for the Study of Diabetic Neuropathy

Widely Used and Frequently Published
Our Pain and Inflammation Research Antibodies have proven valuable for the study of neuropathic, nociceptive and inflammatory pain.

This recent publication is focused on Diabetic Neuropathy. José Eduardo Roa-Coria, Jorge Baruch Pineda-Farias, Paulino Barragán-Iglesias, Geovanna Nallely Quiñonez-Bastidas, Ángel Zúñiga-Romero, Juan Carlos Huerta-Cruz, Juan Gerardo Reyes-García, Francisco Javier Flores-Murrieta, Vinicio Granados-SotoView ORCID ID profile and Héctor Isaac Rocha-González (2019). Possible involvement of peripheral TRP channels in the hydrogen sulfide-induced hyperalgesia in diabetic rats. BMC Neuroscience 201920:1 https://doi.org/10.1186/s12868-018-0483-3.

The results show Hydrogen Sulfide (H2S) catalyzes hyperalgesia in rats via TRP Channels. Our Substance P is used in the study.


Figure: Immunolocalization of cystathionin-β-synthase enzyme (CBS, red) with a–e neuronal nuclear antigen (NeuN)-, f–j substance P (SP)-, k–o isolectin B4 (IB4)- and p–t glial fibrillary acidic protein (GFAP)-positive dorsal root ganglion neurons of diabetic rats (green). a, f, k and p show a representative 16 µm-slice from dorsal root ganglia. b, g, l and q show a representative CBS staining with Cy3 from dorsal root neurons, whereas c, h, m and r show NeuN, SP, IB4 and GFAP representative staining with Cy2 in dorsal root neurons, respectively. d, i, n and s show the merged image from Cy3 and Cy2 signals, the overlapping between CBS and neuronal markers is shown in a yellow-orange color. e, j, o and t show a magnification of d, i, n and s, respectively.


The authors conclude that H2S leads to hyperalgesia in diabetic rats through activation of TRPV1, TRPA1 and TRPC channels and, subsequent intraepidermal fibers loss. CBS enzyme inhibitors or TRP-channel blockers could be useful for the treatment of painful diabetic neuropathy.

Rat Hippocampal Neurons

Used to Study Apoptosis Induced by Brain Insults
Although our primary human cells are increasingly being used in drug discovery and toxicology assays versus animal cells, we are always pleased to see the success of the latter in sophisticated studies.

This publication references use of our e18 rat hippocampal neurons. These cells continue to be easy to culture, pure and potent. Chiara Porro, Antonia Cianciulli, Teresa Trotta, Dario Domenico Lofrumento, Rosa Calvello and Maria Antonietta Panaro. (2019). Formyl-methionyl-leucyl-phenylalanine Induces Apoptosis in Murine Neurons: Evidence for NO-Dependent Caspase-9 Activation. Biology 8(1), 4; doi:10.3390/biology8010004.

Highlights
Formyl-methionyl-leucyl-phenylalanine (fMLP) may be present in the brain in the course of some infectious diseases of the central nervous system (CNS), although little is known about its role. This investigation was performed to study the effect of fMLP on neuron apoptosis. The results showed that fMLP treatment of primary cultures of neurons was able to induce morphological features of apoptosis in cell cultures, as well as activation of the intrinsic apoptotic pathway, through the upregulation of caspase-9 and caspase-3.

Figure. (A) Western blot analysis was performed on membrane-enriched cell extracts (25 µg lysate) of primary neurons. The blots were probed with formyl peptide receptor 2 (FPR2) antibody (Ab) and detected by chemiluminescence. A ~41 kDa band corresponding to FPR2 was observed as compared to the positive control. Lane 1: Marker; lane 2: Positive control, lane 3: Primary neuron lysate. (B) Immunofluorescence identification of FPR. Double staining shows the expression of the FPR receptor on the cell membrane and neurofilaments. FPR2 expression (green); skeleton protein staining of neuron-specific neurofilament 68 (red); DAPI nuclear staining (blue); cells stained by both neurofilament 68, FPR2 and DAPI (merged). Scale bar: 100 μm. 1): neurofilaments stain; 2) FPR2 expression; 3) DAPI stain; 4) merged.

The present study emphasizing the potential role of infectious agents, such as N-formyl peptides, in neurodegenerative diseases may help to promote the development of new therapies able to modulate the expression of the N-formyl peptide receptors.

Human Primary Cells Trifecta

Tri-culture of Neuromics' Human Primary Cells in 3-D BBB Model

I mentioned in an earlier post that we take Researchers questioning the validity of our Human Primary Cells very seriously. We follow up with our clients to make sure our cells are working as expected. If they are not 100% happy, we offer a free replacement or full refund.

...So it is encouraging to see Researchers using our Human PericytesBrain Microvascular Endothelial Cells (HBMES) and Astrocytes to build a static 3-D Blood-Brain Barrier Model.

Primary Human Brain Pericytes

Pure and Potent
The authors of a chapter on pericytes published in SpringerLink referred to our human primary pericytes as "pericyte-like", but chose not to characterize them because of the "exorbitant cost". Dore-Duffy P., Esen N. (2018) The Microvascular Pericyte: Approaches to Isolation, Characterization, and Cultivation. In: Birbrair A. (eds) Pericyte Biology - Novel Concepts. Advances in Experimental Medicine and Biology, vol 1109. Springer, Cham

Given that these pericytes are also part of our hot selling 3-D Human BBB Model, we are in the process of challenging these claims. We will always take inaccurate claims regarding our solutions seriously, and we take immediate action.
  • Characterization of cells-we validated several key markers by immunofluorescence.


Staining of Desmin (dilution 1:100). Secondary antibody conjugated to Alexa 594 (red) and counterstained with DAPI (blue). Cells were mounted using iBrite mounting media.

Staining of Actin (dilution 25 ug/mL). Secondary antibody conjugated to Alexa 594 (red) and counterstained with DAPI (blue). Cells were mounted using iBrite mounting media.
We also plan on doing a phenotypic analysis of these cells and will post here when completed.
  • Cost of cells-isolating pericytes from human donors, and expanding to the required number of cells involves much time and effort. We know! Further differentiating stem cells into pericytes is hard and time-consuming. Against this backdrop, we consider our pricing to be inexpensive. Though they are more difficult to derive, they are priced equivalently with our other human primary cells ($789/500,000 USD Cells).
As always, we will post new data here.

Pain Receptors and Diabetic Neuropathy

We Got the Markers
Our Markers for Pain Research are widely used and frequently published. They are often referenced in publications on Diabetic nerve pain.

Here are some of my past blog postings:
Here's a model of the actual nerve receptors behind both intractable pain and loss of sensation.
A: Simplified model of nociception under normal conditions. Free nerve endings transduce a painful stimulus into a neural signal, which propagates to DRG centrally and eventually synapses on a nociceptive neuron within the DH of the spinal cord.B: Proposed model of nociception under conditions of diabetic hyperalgesia and allodynia. A pain signal augmented by upregulated pronociceptive ion channels in sensory neurons is carried toward the DH, where it is further augmented by a hypoactive GABAergic system and subsequently diminished inhibition from an inhibitory interneuron. NMDAR, N-Methyl-D-aspartate receptors. https://doi.org/10.2337/dbi15-0006
We will continue to post findings on the root causes and potential treatment for Neuropathy.

Quality FBS-Only 259 USD/500 ml.

First Come; First Serve
We have an inventory of FBS of approximately 2000 bottles.  This inventory includes the lots we've been selling and using internally all year.  These have proven to be of the highest quality.
Here’s a sampling of user feedback: 
  • After a referral from an ex-colleague, we tested a sample from a single batch and found that the product is great for cell cloning & hybridoma work, and generally for all other cell culture. We subsequently ordered several bottles of FBS. The sales person was very friendly and worked with me to make the purchase possible. The order arrived promptly. - Peter Dias, The Biomedical Research Institute of SC
  • We ordered several bottles of Fetal Bovine Serum on 2 occasions and are pleased with its performance in our cultures. The FBS arrived frozen in enough dry ice and was neatly and carefully packed. The FBS was very reasonably priced. Thank you. - Ken Patrene, University of Pittsburgh

GREM-1 is required for tube formation in vitro (A) Q-RT-PCR analysis of GREM-1 gene expression in SU-DIPG-IV cells stably expressing either control shRNA or GREM-1-specific shRNA. Lentiviral constructs expressing two different GREM-1 shRNAs (GREM-1.1 and GREM-1.2) were used to knockdown GREM-1. Efficiency of GREM-1 knockdown was determined by Q-RT-PCR and expression was normalized to 18s RNA. Significance is as shown (**less than.01). (B-C) HUVEC or human brain microvascular endothelial cells (HBMEC) were cultured in endothelial cell medium and or conditioned medium from either control shRNA or shGREM-1.2 transfected SU-DIPG-IV cells. Tube formation in matrigel was measured after 16h and images were obtained. The ability of GREM-1 to rescue loss of tube formation upon REST knockdown was determined by addition of human-recombinant GREM-1 (rGREM-1) to conditioned media-endothelial media mix. Scale bars, 100μm. (C) Quantification of tubes in matrigel shown in Figure B (right panels). Data shown is mean +/- SD, ***p less than .001, n=3. (D) Western blot analysis to assess VEGFR2 levels in SU-DIPG-IV, -VI and –XIII cells, HUVECs and HBMECs was done using anti-VEGFR2 antibodies. Tubulin served as a loading control. (E) Western blot analysis was performed to assess AKT signaling downstream of GREM-1 interaction with its potential receptor VEGFR2 in HUVEC and HBMEC. Anti-pAKT (S473), anti-pAKT (T308), total AKT, and anti-actin were employed.

Energize your Cell-Based Assays

Check out our AlphaBioCoat 
Collagen is a fibrous protein found in the extracellular matrix and connective tissue. The most common form of collagen is type I and is most prevalent in bone, tendon and skin. It consists of 3 intertwined coiled subunits: 2 x α1 (I) chains and 1 x α2 (I) chain. Each chain contains 1050 amino acids wound tightly around one another in a characteristic right-handed triple helix. The triple-helical structure of collagen arises from unique abundance of the amino acids in collagen appear in a characteristic repeating motif Gly-X-Y, where X is usually proline and Y is usually hydroxyproline.

AlphaBioCoat Solution (AC001) is a biocompatible complex of extracellular matrix binding solution that is supplemented with growth factors. It helps accelerate cell attachment and cell growth. AC001 is the premium version of our Smooth Coat Solution (SC300).

It is ideal for plate coating due to its unique viscosity. Its coating greatly enables cell migration on cultured plate surfaces. Perfect for establishing primary cell lines, it can increase endothelial cell attachment, survival in culture, and cell growth. AlphaBioCoat Solution is great for both coating plates and T-flasks.

Our Hearing Adapts in Space

Synaptic Plasticity in the Ear
Our mission to Mars is driving a need to better understand the physiological impact on the human body. Deep space travel places unique challenges for humans. It is important that there is minimal impact on space travelers' senses. This includes hearing.

This study uses our Shank 1a Antibody to determine changes in the neuronal structure of the ear in microgravity.

Image: Verification of antibodies to CtBP2 and Shank1a. A and B: serial 14-µm cryosections were obtained from a postnatal day 71 (P71) mouse utricle, and maximum-intensity projections are shown. Hair cell (hc) and support cell (sc) nuclei are illuminated by the DAPI stain (blue). Numerous closely associated CtBP2-and Shank1a-positive puncta can be observed in the positive immunostained section represented in A (block arrowheads). The CtBP2-positive puncta highlighted by the flared arrowhead in A may represent an undocked synaptic ribbon. No primary antibodies were included in the processing represented in the micrograph in B. The scale bar in B represents 5 µm and also applies to A. C and D: maximum-intensity projection micrographs from right and left whole mount utricles from a P65 mouse. Importantly, fixative administration into the temporal bones yielding the specimens represented in C and D was delayed 7 min to replicate the conditions associated with specimens derived from the microgravity and control specimens. The positive-immunostained specimen of the pair is shown in C, where numerous closely associated CtBP2-positive and Shank1a-positive puncta can be observed. Though faint, CtBP2-immunostained nuclei are highlighted by the flared arrowheads. The micrograph in D illustrates the results of withholding primary antibodies from the processing. Immunolabeled puncta are not observed. The scale bar in D represents 5 µm and also applies to C. https://www.physiology.org/doi/full/10.1152/jn.00240.2016 

These results demonstrate that structural plasticity was topographically localized to the utricular region that encodes very low frequency and static changes in linear acceleration, and illuminates the remarkable capabilities of utricular hair cells for synaptic plasticity in adapting to novel gravitational environments.

Staining Cells and Tissue

The background is Bad!
Yes, it is. It compromises data. We have a solution.
FluoMuteTM

FluoMute™ ready-to-use reagent to reduce autofluorescence in cells and tissue. Just incubate fixed cells of tissue sections with FluoMute™ for 30-60 min at room temperature, rinse with PBS and continue with immunofluorescence ICC or/and IHC protocols. Treatment with FluoMute™ does not affect cell morphology and the integrity of tissue antigens to be detected with primary antibodies (see bottom image). FluoMute™ is compatible with paraffin-embedded and frozen tissue sections, stem cells, lymphocytes and mammalian cell lines of different origin.

We plan on adding products that will provide stronger signals with fewer protocols steps vs traditional solutions. Stay tuned.
