Cell Meter™ Caspase 8 Activity Apoptosis Assay Kit
Blue Fluorescence
Our Cell Meter™ assay kits are a set of tools for monitoring cellular functions. There are a variety of parameters that can be used to monitor cell apoptosis. This particular kit is designed to monitor cell apoptosis by measuring caspase 8 activity. Caspase 8 is a caspase protein, encoded by the CASP8 gene. Caspase 8 also plays an important role in neurodegenerative diseases such as Huntington disease. Caspase 8 is proven to have substrate selectivity for the peptide sequence Ile-Glu-Thr-Asp (IETD). This kit uses (Ac-IETD)-AMC as a fluorogenic indicator for caspase 8 activity. Cleavage of AMC peptides by caspase 8 generates strongly fluorescent AMC. This spectral feature makes the kit compatible with the DAPI filter set. The kit provides all the essential components with an optimized assay protocol. The assay can be readily adapted for high throughput screenings. It can be used to either quantify the activated caspase 8 activities in apoptotic cells or screen the caspase 8 inhibitors.
Detection of caspase 8 activity in Jurkat cells using Cell Meter™ Caspase 8 Activity Apoptosis Assay Kit *Blue Fluorescence*. Jurkat cells were seeded on the same day at 200,000 cells/90 µL/well in a Costar black wall/clear bottom 96-well plate. The cells were treated with or without 1 µM of staurosporine for 5 hours. The caspase 8 working solution (100 µL/well) was added and incubated at room temperature for 30 minutes. The fluorescence intensity was measured at Ex/Em = 370/450 nm (Cutoff = 420 nm) with a FlexStation™ microplate reader (Molecular Devices).
