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.

Autophagy Assay Kits

Detects Autophagy in Living Cells
Autophagy is a conserved lysosomal recycling process by which cells break down their own components such as proteins, lipids, and carbohydrates. The process plays an important role in maintaining homeostasis and destroying intracellular pathogens. In addition, autophagy can be upregulated in times of starvation or stress to provide additional nutrients for the cell. Dysregulation of autophagy has implications for cancer, infection, and degenerative diseases.

Autophagy is a three-stage process. First, cytoplasmic components targeted for degradation are sequestered, resulting in the formation of the autophagosome. Next, the autophagosome fuses with the lysosome to form the autophagolysosome or autolysosome. Finally, degradation of the autophagosomal contents occurs.

Our Autophagy Assay, Red (cat# KF17373) enables researchers to detect and monitor the in vitro development of autophagy in living cells. The Autophagy Probe is cell-permeant and fluoresces red when inserted in the lipid membranes of autophagosomes and autolysosomes. Results can be read using a flow cytometer.
Figure. Flow Cytometry Results. Autophagy Assay Kit, Red was used to assess the induction of autophagy in Jurkat cells. Cells were either untreated (Black) or treated with 0.5 μM Rapamycin (Orange), 10 μM Chloroquine (Blue), or both 0.5 μM Rapamycin and 10 μM Chloroquine (Red) for 18 hours. After staining with Autophagy Probe, Red for 60 minutes, cells were washed and analyzed by flow cytometry (BD LSRFortessa Special Order flow cytometer equipped with a green/yellow laser (561 nm excitation) and a 610/20 emission filter). An overlay of the histograms is shown on the right. A table displaying the median fluorescence signal, % negative, and % positive cells is shown below. Treatment with Rapamycin or chloroquine increased the fluorescence signal detected compared to the untreated control. Combined treatment of rapamycin and chloroquine further increased the fluorescence signal detected. Data courtesy of Dr. Kristi Strandberg (ICT 228:37-40).

We have many options for detecting apoptosis, necrosis, autophagy, and cytotoxicity in living cells.

Markers for Tyrosine Hydroxylase-TH

Proven and Published
Tyrosine hydroxylase TH is a necessary enzyme to create neurotransmitters and protect the body against oxidative stress.

Dysregulation of this enzyme results in manic-depression and schizophrenia. Parkinson's disease is also considered a TH deficiency as low dopamine levels are a consistent neurochemical abnormality.

Markers to TH are important for studying its role in neurotransmission and how it is altered in disorders and diseases.

We have many options and this enables you to choose the best markers for your research. All are proven and published.

New Fibrillarin Antibody

Potent Nucleoli Marker
Given the importance of Nucleus and Related Markers to all branches of cell/molecular biology, we are dedicated to having the best.

We have just added a new Fibrillarin Antibody.
Images: Immunofluorescent analysis of (A) C6 rat glioma cells and (B) Human embryonic kidney cells stained with mouse mAb to fibrillarin, MO22169, dilution 1:1,000 in red, in both cases costained with chicken pAb to vimentin, CPCA-Vim, dilution 1:10,000 in green. The blue is DAPI staining of nuclear DNA.

Nop1p/Fibrillarin was originally identified as a nucleolar protein of bakers yeast, Saccharomyces cerevisiae (accession P15646). The Nop1p protein is 327 amino acids in size (34.5kDa), is essential for yeast viability, and is localized in the nucleoli. Nop1p is the yeast homolog of a protein apparently found in all eukaryotes and archaea generally called fibrillarin. Fibrillarin/Nop1p is extraordinarily conserved so that the yeast and human proteins are 67% identical, and the human protein can functionally replace the yeast protein. This antibody is becoming widely used as a convenient marker for nucleoli in a wide variety of species (e.g. 4-6). The HGNC name for this protein is FBL. To raise the MCA-4H4 antibody, mice were injected with full length recombinant human fibrillarin.

Fibroblast Compression and Tumor Cells Migration

Role of Compression in Metastasis
Our Human Pancreatic Fibroblasts play a key role in this study.

Pancreatic fibroblasts are continuously gaining ground as an important component of tumor microenvironment that dynamically interact with cancer cells to promote tumor progression. In addition, these tumor-infiltrated fibroblasts can acquire an activated phenotype and produce excessive amounts of extracellular matrix creating a highly dense stroma, a situation known as desmoplasia. Maria Kalli, Panagiotis Papageorgis, Vasiliki Gkretsi, Triantafyllos Stylianopoulos. (2018). Solid Stress Facilitates Fibroblasts Activation to Promote Pancreatic Cancer Cell Migration. Annals of Biomedical Engineering. https://doi.org/10.1007/s10439-018-1997-7.

FIGURE 1. A schematic of the in vitro transmembrane pressure device. (a) Fibroblasts were grown as a monolayer on the transmembrane of a 0.4 lm transwell insert and a piston of adjustable weight was applying a compressive stress. Control cells were covered with an agarose cushion only. (b) The experimental set-up of the co-culture system consisted of fibroblasts and pancreatic cancer cells (MIA PaCa-2 or CFPAC-1) in the upper and lower chamber of a transwell insert, respectively. A piston with adjustable weight, applying 4.0 mmHg of compressive stress on fibroblasts for 48 h is shown. A co-culture system consisting of fibroblasts and cancer cells without a compressive load was used as a control.

Solid stress developed within tumors is able by itself to activate normal fibroblasts, which in turn produce excessive amounts of ECM proteins leading to desmoplasia.

ATP and Pain

P2XRs Play a Key Role
In dorsal root ganglion (DRG) neurons, ATP is an important neurotransmitter in nociceptive signaling through P2 receptors (P2Rs) such as P2X2/3R, and adenosine is also involved in anti-nociceptive signaling through adenosine A1R.

ENNPs interact with P2XRs to metabolize ATP to AMP in DRGs. Kentaro Nishida, Yuka Nomura, Kanako Kawamori, Akihiro Ohishi, Kazuki Nagasawa. ATP metabolizing enzymes ENPP1, 2 and 3 are localized in sensory neurons of rat dorsal root ganglion. European Journal of Histochemistry 2018; 62:2877.

Unmasking Root Causes of Stress/Anxiety

i-Fect Knocks Down Suspected Stress/Anxiety Receptor
The molecular pathogenesis underlying anxiety disorders is still unclear. Here, the authors demonstrate that myristoylated alanine-rich C-kinase substrate like 1 (MARCKSL1) overexpression in mice increases spine formation in the amygdala and induces stress hormone upregulation and anxiety-like behaviors. Suppression of MARCKSL1 in the amygdala ameliorates both the increase in stress hormones and the elevated anxiety-like behaviors. Our results indicate that MARCKSL1 expression in the amygdala plays an important role in anxiety-like behaviors.

This was proved, in part, by the knockdown of MARCKSL1 in vivo in mice using our i-FectTM. Tanaka, Takashi; Shimizu, Shoko; Ueno, Masaki; Fujihara, Yoshitaka; Ikawa, Masahito; Miyata, Shingo. MARCKSL1 Regulates Spine Formation in the Amygdala and Controls the Hypothalamic-Pituitary-Adrenal Axis and Anxiety-Like Behaviors. https://doi.org/10.1016/j.ebiom.2018.03.018

Figure: Knockdown of MARCKSL1 ameliorates anxiety-like behavior in MARCKSL1 Tg mice. (A and B) For the in vivo experiment, siRNA (blue) was injected into the CeA (total 4 sites) with i-Fect siRNA transfection reagents 5 days prior to behavioral tests. (C) In situ hybridization for Marcksl1 mRNA (blue) in the amygdala after injection of Marcksl1 siRNA into the CeA of Tg/Tg mice. Scale bar, 200 μm.

HUVECS in 3-D Action

Form Vascular Networks in Microfluidics Model
In this study, the authors developed a 3D functional human microvascular network in a microfluidic device. The established model enables Neuromics GFP-labeled human umbilical vein endothelial cells to form vessel-like microtissues and have physiological functions which are closer to cells in human blood vessels. The perfusable microvasculature allows the delivery of nutrients, and oxygen, as well as flow-induced mechanical stimuli into the luminal space of the endothelium. The microflow effectively mimic the blood flow in human vessels.

This in-vivo like model is then used for toxicity assays-Yan Li, Qing-Meng Pi, Peng-Cheng Wang, Lie-Ju Liu, Zheng-Gang Han,Yang Shao, Ying Zhai, Zheng-Yu Zuo, Zhi-Yong Gong, Xu Yang and Yang Wu.

Primary Human Astrocytes vs Derived Astrocytes Cell Lines

Potent, Pure and Easy to Culture

We are often asked how our human primary astrocytes stack up versus engineered astrocyte cell lines. Astrocyte cultures, whether primary or engineered, need to mimic how they work in-vivo.

This publication is a comprehensive study of the capabilities of our primary astrocytes versus engineered cells. Anders Lundin, Louise Delsing, Maryam Clausen, Piero Ricchiuto, José Sanchez, Alan Sabirsh, Mei Ding, Jane Synnergren, Henrik Zetterberg, Gabriella Brolén, Ryan Hicks, Anna Herland, and Anna Falk.

DOI: https://doi.org/10.1016/j.stemcr.2018.01.021.

With the exception of glutamate uptake, our primary cells talk and walk like astrocytes. We do plan on running assays to test for glutamate uptake as we believe the cells are capable.

It is important that all our human neurons, astrocytes, microglia and schwann cells are potent, pure and easy to culture. As you can see from this graphic, our "primary astros" our positive for most the required characteristics.

i-Fect Delivers Again and Again

Silencing Lactate Dehydrogenase A in vivo

Pathologic CNS is characterized by neuronal damage that leads to the release of intracellular components. However, the effect of damaged cells on angiogenesis has not been clarified. This study revealed that LDHA, which is a known damage marker, promotes CNS-specific angiogenesis. LDHA-mediated angiogenesis depends on vimentin on the surface of vascular endothelial cells. The work described here proposes a novel mechanism by which neurodegeneration drives angiogenesis in the CNS.

A mixture of our i-FectTM and LDHA siRNA, in this study, were directly injected into mice cortexes: Hsiaoyun Lin, Rieko Muramatsu, Noriko Maedera, Hiroto Tsunematsu, Machika Hamaguchi, Yoshihisa Koyama, Mariko Kuroda, Kenji Ono, Makoto Sawada, Toshihide Yamashita.

Culturing Cells in Defined 3-D Structures

Media Supplements Matter

There have been several publications referencing use of our growth factors in 3-D Cultures. It is important that potent growth factors are used to ensure proper cell growth and differentiation.

Here's a new publication referencing use of our ISOKineTM FGF. Our ISOKine growth factors are produced in the endosperm tissue of barley grain (Hordeum vulgare), that exhibits up to 50 times less protease activity than E.coli or mammalian cells. Barley seed is void of any human or animal viral contaminants that could jeopardize your cell culture.

Claas Willem Visser, Tom Kamperman, Lisanne P. Karbaat, Detlef Lohse and Marcel Karperien. In-air microfluidics enables rapid fabrication of emulsions, suspensions, and 3D modular (bio)materials. Science Advances 31 Jan 2018: Vol. 4, no. 1, eaao1175 DOI: 10.1126/sciadv.aao1175. In this study, the authors present in-air microfluidics (IAMF), a new chip-free platform technology that enables in-flight (that is, on-the-fly) formation of droplets, fibers, and particles and their one-step deposition into 3D constructs with a modular internal architecture.
Figure: Concept of IAMF and guide to the article. (A) Chip-based microfluidics enables in-line control over droplets and particles, making it a versatile platform technology. A chip design where droplets (blue) are transported by a coflow (pink) is shown. (B) IAMF maintains the in-line control of chip-based microfluidics but relies on jet ejection and coalescence into air. Therefore, a wide range of droplets and particles can be produced at flow rates typically two orders of magnitude higher than with chip-based microfluidics. When combining reactive, solidifying microjets, IAMF also enables on-the-fly production and direct deposition of microparticles into 3D multiscale modular (bio)materials.

Figure: One-step additive manufacturing and injection molding of 3D multiscale modular (bio)materials. (A) Modular free forms with a controlled microarchitecture were manufactured by stacking of shape-stable core-shell particles. (B to D) A hollow cylinder was formed by deposition of the composite jet onto a rotating substrate. By altering the building blocks’ composition, the resulting microarchitecture consisted of (C) a liquid-filled foam or (D) a multimaterial modular solid, where the cross-linker for the core was added to the shell and vice versa. (E) To eject a modular filler, only the droplets’ cores are solidified in the air, whereas the slower solidifying shells enable seamless filling of the mold. (F to H) A modular construct was produced by filling a bone-shaped mold. Inset: Hydrogel construct while still in the mold. The 3D multiscale modular material consisted of MSCs (pink), encapsulated in alginate microspheres (green) that are embedded in dextran-tyramine hydrogel (red). (I) Injection-molded multiscale modular tissue construct with optimized cellular micro- and macroenvironments. The construct consisted of insulin-producing pancreatic β cells (MIN6; beige with blue nuclei) that were encapsulated in alginate microparticles (green). The cell-laden microparticles were encapsulated within a proangiogenic fibrin network that contained human endothelial and stem cells (pink with blue nuclei). The microenvironments supported MIN6 cell proliferation, whereas the macroenvironment supported the formation of an endothelial cellular network within 7 days of in vitro culture.

Culturing Neurons on Conductive Biomaterials

Neuromics' Neurons on Graphene
Conductive biomaterials are an ideal bio-substrate for modifying cellular behaviors by conducting either internal or external electrical signals.

In this study, researchers successfully culture our cortical neurons on Nonfunctionalized graphene nanosheets (NGN): Shiyun Meng, Rong Peng. Growth and Follow-Up of Primary Cortical Neuron Cells on Nonfunctionalized Graphene Nanosheet Film. Article first published online: January 18, 2018. https://doi.org/10.5301/jabfm.5000263.
Figure: Spray-coating a nonfunctionalized graphene nanosheet (NGN) on a glass slide. To fix the NGN onto the glass slide, polyurethane (PU) was firstly spin-coated onto glass slides as a polymer matrix, then NGN particles were spray-coated on by airbrush.
Figure: Nuclei formed in 7 and 14 days of cell culture are shown at a relatively high magnification (scale bar = 50 μm): 1/500 MAP-2 (H-300) and 1/500 Alexa Fluor® 488 anti-Rabbit stained green for neuron microtubules and DAPI stained blue neuron nuclei.

We have a large catalog of potent, proven and pure human and animal cells.

Cells from Diseased Donors

Focus on Neuro Diseases

We now have the capability to provide cells of the central and peripheral nervous system from donors with Neuro diseases. These include cells from donors with ALS, AD, PD, and Brain Cancer Donors, to name a few.


We have provided cells to virtually all the large Pharmas and many small and mid-size Bio-techs. We have worked with Novartis to gain 21-CFR compliance for cells that they are using for their eye diseases drug discovery programs.

I am at your “beck and call” should you have interested in exploring specific capabilities further. You can e-mail or call me at 612-801-1007

Figure: Connexin43 (green) and GFAP (red) expression in normal and human DR donor retinas in regions of extensive vascular damage. Large cells (white arrows, left column) represent non-specific auto-fluorescent amacrine cells. Connexin43 expression was markedly higher in the GCL of DR donor tissues compared to age-matched controls, and was strongly expressed throughout all retinal layers. GFAP labeling was also markedly higher in DR compared to normal donor eyes representing hyper-reactive Müller cells. Connexin43 expression was increased in regions identified as blood vessels and correlated with increased GFAP labeling at these sites, indicating glial cell activation (white circle). GCL = ganglion cell layer; IPL = inner plexiform layer; INL = inner nuclear layer; OPL = outer plexiform layer; ONL = outer nuclear layer. Scale bar: 200 µm

Medical Grade Soluble Collagen

New Products-New Applications

We are pleased to announce the addition of  Medical Grade Collagen to our Cell Based Assay Solutions. Applications include:
  • Tissue engineering 
  • Wound healing
  • Medical device coatings
  • 3D cell cultures
  • Drug delivery 
  • Sealants 
  • Electrospinning
  • Hemostats
  • 3D printing
This example outlines how this collagen can be used for cartilage regeneration from mesenschymal stem cells. Acta Biomater. 2016 Jan;30:212-221. doi: 10.1016/j.actbio.2015.11.024. Epub 2015 Nov 18.

Figure: Fabrication of macroporous woven scaffolds and pellet delivery via the macroporous woven collagen scaffold; (a) Liquid to solid phase transition of collagen molecules via electrocompaction to fabricate electrochemically aligned collagen threads and electrocompacted sheets. (b) Collagen thread is woven around a set of pins and threads are stabilized by crosslinking two collagen sheets on top and bottom of woven part of scaffold. (c) Schema of the final woven collagen scaffold. (d) 1 million MSCs pelletized at 500 ×g for 12 minutes, cultured for 3 days and then transferred in to scaffold holes.
SIGNIFICANCE: Mesenchymal condensation is critical for driving chondrogenesis, making high density cell seeding a standard in cartilage tissue engineering. Efforts to date have utilized scaffold free delivery of MSCs in pellet form. This study developed a macroporous scaffold that is fabricated by weaving highly aligned collagen threads. The scaffold can deliver high density cell condensates while providing mechanical stiffness comparable to that of cartilage. The scaffold also mimicked the arcade-like orientation of collagen fibers in cartilage. A highly robust chondrogenesis was observed in this mesenchymal cell pellet delivery system. Baseline mechanical robustness of this scaffold system will enable delivery of cell pellets as early as three days.
