Background Information

Caspase 4 (CASP4), is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis.Caspase 4 is able to cleave and activate its own precursor protein, as well as caspase 1 precursor. Overexpression of caspase 4 will induce cell apoptosis.

This is a great antibody. Work very efficiently if you use it as the first antibody (worse less well if your membrane has already been deactivated with Peroxide). This product also detect efficiently cleaved Caspase-4 (which can be very challenging with other antibodies)
