Protocols
- 9492:
- Western Blotting
Specificity / Sensitivity
Caspase-7 Antibody detects endogenous levels of both full length caspase-7 (35 kDa) and the large fragment of cleaved caspase-7 following cleavage at aspartic acid 198 (20 kDa). The antibody does not recognize other caspases.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the cleavage site of human caspase-7. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from Jurkat cells, untreated or etoposide-treated (25 µM), and HeLa cells, untreated or staurosporine-treated (1 µM), using Caspase-7 Antibody.
Background
Caspase-7 (CMH-1, Mch3, ICE-LAP3) has been identified as a major contributor to the execution of apoptosis (1-4). Caspase-7, like caspase-3, is an effector caspase that is responsible for cleaving downstream substrates such as (ADP-ribose) polymerase and PARP (1,3). During apoptosis, caspase-7 is activated through proteolytic processsing by upstream caspases at Asp23, Asp198, and Asp206 to produce the mature subunits (1,3). Similar to caspase-2 and -3, caspase-7 preferentially cleaves substrates following the recognition sequence DEVD (5).
