Caspase-3 (8G10) Rabbit mAb #9665
|W IP||H M R Mk||Endogenous||17, 19, 35||Rabbit IgG|
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.
Specificity / Sensitivity
Caspase-3 (8G10) Rabbit mAb detects endogenous levels of full-length (35 kDa) and large fragment (17/19 kDa) of caspase-3 resulting from cleavage at aspartic acid 175.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to amino-terminal residues adjacent to (Asp175) in human caspase-3.
Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 (-) or SignalSilence® Caspase-3 siRNA II (+), using Caspase-3 (8G10) Rabbit mAb and α-Tubulin (11H10) Rabbit mAb #2125. Caspase-3 (8G10) Rabbit mAb confirms silencing of caspase-3 expression, while the α-Tubulin (11H10) Rabbit mAb is used to control for loading and specificity of caspase-3 siRNA.
Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 (-) or SignalSilence® Caspase-3 siRNA I (+), using Caspase-3 (8G10) Rabbit mAb and p42 MAPK Antibody #9108. Caspase-3 (8G10) Rabbit mAb confirms silencing of caspase-3 expression, while the p42 MAPK Antibody is used to control for loading and specificity of caspase-3 siRNA.
Western analysis of HeLa (human) and NIH/3T3 (mouse) cell extracts, untreated and treated with 1 uM staurosporine (3hrs) in vivo, using Caspase-3 (8G10) Rabbit mAb.
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).
