|IF-IC F||H (M) (R) (Mk) (B) (Pg)||Endogenous||Rabbit IgG|
Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey B=Bovine Pg=Pig
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb recognizes endogenous levels of caspase-3 protein only when cleaved at Asp175.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp175 of human caspase-3 protein.
Flow cytometric analysis of Jurkat cells, untreated (blue) or treated with etoposide #2200 (green), using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb (Alexa Fluor® 488 Conjugate).
Confocal immunofluorescent analysis of HeLa cells, untreated (left), or treated with staurosporine #9953 (right), using Cleaved Caspase-3 (Asp175) (D3E9) (Alexa Fluor® 488 Conjugate) Rabbit mAb (green). Actin filaments have been labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb #9579.
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).
