Apoptosis is a form of self-destruction or programmed cell death provoked by the organism itself. There is a family of proteases that play an important role in programmed cell death. This activity is measured by a short peptide containing specific sequences. These sequences are recognized by the caspase and are covalently attached to a colorimetric or fluorimetric detection probe.
Bioquochem under its brand BQCkit provides a complete line of assay kits focused on measuring caspase activity in cell cultures.
