Product Overview
Clone HE-3 is a rabbit monoclonal antibody that recognizes caspase-3 (gene CASP3) in human samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 31.6 kDa, and the supplier reports an observed band at about 17 kDa.
Caspase-3 is the major executioner caspase of apoptosis. Activated by initiator caspases such as caspase-8 and caspase-9, it cleaves hundreds of cellular proteins, including PARP1, leading to the typical features of apoptotic cell death. Cleaved (active) caspase-3 is one of the most widely used apoptosis markers in Western blot and immunohistochemistry.
