Cell Death / Health Assays Products & Reviews

In 2008 Gentronix launches a new S9 protocol to extend the application of the GreenScreen HC assay to include the detection of genotoxic metabolites. Many pharmaceuticals only present a genotoxicity hazard after metabolism and such chemicals are called pro-mutagens or pro-genotoxins. Generally, although not exclusively, the liver is considered responsible for the “metabolic activation” (MA) of promutagens. However, none of t…

ATP luminescence assay for quantitative evaluation of proliferation and cytotoxicity of cultured mammalian cells. The 1step luciferase ATP assay format only requires one addition step, and can be used for continuous processing.

EZ4U-Cell Proliferation & Cytotoxicity Assay

Real-Time qPCR assays for Apoptosis and related genes reformatted onto an OpenArray plate. Kit includes: OpenArray plate,…

R&D Stem Cell Kits and Panels Research in developmental biology has led to the discovery of several types of stem cells, including embryonic stem (ES) cells, embryonic germ cells, and adult stem cells. Techniques and reagents developed for the in vitro culture, manipulation and characterization of stem cells provide unprecedented opportunities to study embryology and develop disease treatments. R&D Systems offers the follow…

R&D Flow Cytometry Kit - Flow cytometry kits designed for analysis of cell populations use up to four fluorochrome-conjugated antibodies. Flow cytometry facilitates quantitative, multiparameter analysis of cell populations based on the expression of cell surface and/or intracellular molecules. R&D Systems offers a wide range of biotin-, fluorescein-, phycoerythrin-, or allophycocyanin-conjugated monoclonal antibodies specific…

Guava Mitochondrial Depolarization Assay for detection of early apoptosis. There is growing interest within the scientific community to evaluate changes in the mitochondrial membrane potential and further define its role in initiating apoptosis, cell cycle, and other cellular processes. Automated single-cell analysis is the technique of choice due to its sensitivity and high reproducibility. Guava Technologies has optimized an…

The Guava Caspase Assay Suite of fluorescent-based assays for Caspase 3/7, 8, 9 and multi-caspase employ the same protocol making it easier to perform multiple caspase assays in parallel. Further, Guava caspase reagents are membrane permeable allowing one to measure intracellular levels of the enzyme without using harsh lysis methods. The Guava Caspase Assays employ a FLICA (Fluorescent Labeled Inhibitor of Caspase) reagent th…

This kit enables simultaneous measurements in the same cell of six independent parameters that monitor cell health, including cell loss, nuclear size and morphological changes, mitochondrial membrane potential changes, cytochrome c release, and changes in cell permeability.

The BrdU and Ki67 Cell Proliferation HCS Reagent Kits are for simultaneous quantification of DNA replication and Ki67 proliferation marker in the same cell.

The Multiparameter Cell Death Detection Kits for high-content screening (HCS) enable simultaneous quantitation of LC3B protein on autophagic vesicles, cytochrome c localization and its release from mitochrondria, cell membrane integrity and its permeability and nuclear morphology and DNA content.

The micronucleus assay is an important component of genetic toxicology screening programs.  Micronuclei arise from acentric chromosomes and lagging whole chromosomes. 

The Autophagy & Proteasome Function: LC3B and Poly-Ubiquitin Detection Kits enable quantitation of LC3B protein on autophagic vesicles and ubiquitin on polyubiquitinated proteins.

The Cellomics Phospho-ATM Activation Kit contains optimized reagents for the detection and quantitation of phosphorylated ATM (Ser1981) in the nuclei.

The Mitotic Index HCS Reagent Kit provides high-content screening (HCS)-quality fluorescence reagents and a validated protocol for measurement of mitotic index, or the fraction of cells undergoing cell division within a population.

Micro-ruled coverslip for cell culture with microscopic identification and measurement markers.

BlueScreen HC is based on the fast, accurate GreenScreen HC genotoxicity assay from Gentronix Ltd. BlueScreen HC uses the same human-derived, p53-competent TK6 cells to host a patented reporter system that exploits the proper regulation of the GADD45a gene. However, in place of GFP, BlueScreen HC utilizes a luciferase from the marine copepod Gaussia princeps to generate a luminescent output. The BlueScreen luminescent assa…

High Content Analysis (HCA) is rapid, automated microscopy providing quantitative image acquisition and analysis. Using Millipore’s superior-quality reagents in ready-to-use kits and cell-based assays that incorporate the power of HCA, researchers around the world are able to learn more about relevant functional cell biology in many different systems, including assessment of DNA damage and apoptosis. Millipore’s HCA kits inclu…

BlueScreen HC uses a single cell strain, which permits 8 compounds to be tested across 8 dilutions (2-fold serial), together with untreated and positive controls, in one 96-well microplate. After arraying test compounds and dilutions, growing cells are added to each well. For studies without S9 metabolic activation data are collected after incubation (48h) using a multimode microplate reader. For studies incorporating S9 metab…

FasL-Strep, a stable homotrimer, efficiently induces the CD95 pathway of apoptosis and is highly suited for evaluation of CD95 (Fas) receptor-ligand interaction. Human or murine FasL-Strep (CD95L-T4) is an engineered human or murine Fas (CD95) ligand. C-terminal fusion of the T4-FOLDON to the extracellular FasL (CD95L) receptor-binding domain (E142-L281) results in bioactive, conformationally stabilized, well defined trimers…
