Caspase-3 Activation - An Indicator of Apoptosis in Image-Based Assays

.... This protease has been implicated as an effector caspase associated with the initiation of the death cascade and is therefore an important marker of the cells entry point into the apoptotic signaling pathway (Nicholson et al . 1995). Caspase-3 is activated by the upstream caspase-8 and caspase-9 and since...
