ApplicationDuring apoptosis, the activation of specific proteases, called Caspases (cysteinyl-aspartic-acid-proteases), is one of the initial intracellular biochemical events. The Homogeneous Caspases Assay can be used to detect caspase activity in life science research applications: for sensitive quantification of activated caspases for screening of caspase inhibitors as an automatable one-step assay for high-throughp…

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…
