Caspase-3 (p17 subunit) Antibody

The caspases are a group of cysteine enzymes, which cleave proteins in response to intrinsic and extrinsic pathways that cause apoptotic cell death. The caspases can be grouped into two subgroups based on their roles in apoptosis. Initiator caspases (caspases 2, 8, 9, and 10) are activated through the apoptosis-signaling pathways and activate the effector caspases (caspases 3, 6, and 7) which carry out apoptosis. Caspase cascades are initiated through assembly of multiprotein complexes that trigger activation of the initiator caspases, which are then released and are able to activate the downstream effector caspases.

The antibody detects pro Caspase-3 at 32 kDa* and the large subunit of the cleaved form of Caspase-3 at 14-21 kDa. The antibody can be used for western blot, immunohistochemistry and immuno-electron microscopy. The antibody recognizes an epitope in the large domain subunit (p17) of Caspase-3, and it will recognize pro Caspase-3 and the p17 cleavage fragment.
