FLICA™ in vitro Caspase Kits for Apoptosis Assays

Great solution for measuring neurotoxicity

Here's a recent pub confirming the capabilities of our FLICA™ in vitro Caspase Apoptosis Detection Kits: Minghai Zhou, Gregory Ottenberg, Gian Franco Sferrazza, and Corinne Ida Lasmézas Highly neurotoxic monomeric α-helical prion protein. PNAS 2012 109 (8) 3113-3118; published ahead of print February 7, 2012, doi:10.1073/pnas.1118090109. ...PFA and stained for caspases using FLICA polycaspase assay (Neuromics) according to the manufacturer's instructions. Caspases...assayed on live cells using the caspase- specific FLICA assay (Neuromics). Cells were photographed using a Nikon inverted epifluorescence...

Images: FLICA was used to assess cell death in primay rat hippocampal neurons.Cells were plated on 25-mm poly-l-lysine-coated coverslips at 300,000 cells per coverslip. Cells were used at 4 or 8 days in vitro. Composite imagae (A) 3 out of 4 cells are apoptotic (green). No cells were necrotic as both of the PI-positive cells were FLICA-positive; they had compromised membranes and were probably in the late stages of apoptosis rather than necrosis. (B) 3 Caspase-positive cells fluoresce green.

I would like to underscore that we have solutions to cover most your needs for Apoptosis and Cytoxicity Assays. I will continue to post updates on customer data and publications.

High Content and High Throughput Toxicity Screening

Kits designed for Drug Discovery and Development

Our customers have been impressed with the capablities of our in vivo and in vitro apoptosis and toxicity kits. Here's a recent pub referencing use of one of our FLICA™ in vitro Caspase Kits: Giovanna Grandinetti, Nilesh P. Ingle, and Theresa M. Reineke. Interaction of Poly(ethylenimine)–DNA Polyplexes with Mitochondria: Implications for a Mechanism of Cytotoxicity. Mol. Pharmaceutics, Article ASAP Publication Date (Web): June 23, 2011 Copyright © 2011 American Chemical Society...inhibitor of caspases (FLICA) specific for caspase-9 (Neuromics, Inc)...
Images: Jurkat cells were treated with 1 µM staurosporine for 3 hours to induce caspase 9 activity (top), or were treated with a control (bottom). Both populations were incubated with ICT’s green FAM-LEHD-FMK FLICA™ caspase 9 reagent. DIC images were taken of both samples. Almost all cells in the induced sample (top) fluoresce green therefore they have activated caspase 9. None of the control cells (bottom) fluoresce green, therefore they do not have activated caspase 9 Courtesy of Dr. Brian Lee, ICT

Neuromics is pleased to announce the addition of HemoGenix® Predictive in vitro Toxicity and Apoptosis Kits:

Solutions for predictive in vitro toxicity and apoptosis are now important than ever. These kits enable you to do high throughput and high content screening of stem cells, progenitors and primary cells.
Kit options include:

•LumiSTEM™-96 iPS and LumiSTEM™-iPS HT Assays to Study Induced Pluripotent Stem Cells (iPS) and Toxicity to iPS Cells and Cells Derived from iPS Cells.

•LUMENESC™-Tox HT (LUMENESC™-96 Tox and LUMENESC™-384 HT). A Toxicity Screening and Testing Platform for Cells of the Mesenchymal Stem/Stromal Cell System.

•HALO®-Tox HT Predictive Hemotoxicity Platform using HALO®-96 Tox and HALO®-384 HT. A Highly Predictive, In Vitro Stem and Progenitor Cell Hemotoxicity Screening and Testing Platform for all Stages of Drug Development and Xenobiotic.

I will continue to post regarding progress.

Images: Typical confocal photomicrographs of SGN stained with Polycaspase Assay Kit (green) and with an antibody against neuronal III ß-tubulin (red) to identify SGN. (A) In control cultures, most SGN have large, oval shaped soma and neurites extending from the soma; note absence of polycaspase labeling (green). (B) SGN treated for 3 h with 5 mM SS; polycaspase labeling was present on SGN with shrunken soma.
