Immunofluorescent analysis of HeLa cells, untreated (left) or treated with Staurosporine #9953 (1 μM, 4 hr; right), using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb (Alexa Fluor® 594 Conjugate) (red). Actin filaments were labeled with Alexa Fluor® 488 phalloidin #8878 (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).Learn more about how we get our images.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: Cells should be grown, treated, fixed and stained directly in multi-well plates, chamber slides or on coverslips.
Aspirate liquid, then cover cells to a depth of 2–3 mm with 4% formaldehyde diluted in 1X PBS.
NOTE: Formaldehyde is toxic, use only in a fume hood.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb (Alexa Fluor® 594 Conjugate) recognizes endogenous levels of caspase-3 protein only when cleaved at Asp175.

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp175 of human caspase-3 protein.
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 594 fluorescent dye and tested in-house for immunofluorescent 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).
