Applications Key: W=Western Blotting Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Cleaved Caspase-3 (Asp175) (5A1E) Rabbit mAb (Biotinylated) detects endogenous levels of the large fragment (17/19 kDa) of activated caspase-3 resulting from cleavage adjacent to Asp175. This antibody does not recognize full-length caspase-3 or other cleaved caspases.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to amino-terminal residues adjacent to Asp175 of human caspase-3.
Western Blotting
Western blot analysis of extracts from HeLa cells, untreated or treated with Staurosporine #9953 (1 μM, 3 hrs), using Cleaved Caspase-3 (Asp175) (5A1E) Rabbit mAb (Biotinylated) and detected with Streptavidin-HRP #3999.
Description
This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cleaved Caspase-3 (Asp175) (5A1E) Rabbit mAb #9664.
Background
Caspase-3 (CPP-32, Apoptain, Yama, SCA-1) is a critical executioner of apoptosis, as it is either partially or totally responsible for the proteolytic cleavage of many key proteins, such as the nuclear enzyme poly (ADP-ribose) polymerase (PARP) (1). Activation of caspase-3 requires proteolytic processing of its inactive zymogen into activated p17 and p12 fragments. Cleavage of caspase-3 requires the aspartic acid residue at the P1 position (2).
