Detection of Cleaved Caspase‑3 in Jurkat Human Cell Line by Flow Cytometry. Jurkat human acute T cell leukemia cell line untreated (open histogram) or treated with 3 µM Staurosporine for 3 hours (filled histogram) was stained with Rabbit Anti-Human/Mouse Caspase-3 Alexa Fluor® 647-conjugated Monoclonal Antibody (Catalog # IC835R, filled histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with 90% methanol. View our protocol for Staining Intracellular Molecules.
Preparation and Storage
- 12 months from date of receipt, 2 to 8 °C as supplied.
Caspase-3 (Cysteine-aspartic acid protease 3/Casp3; also Yama, apopain and CPP32) is a 29 kDa heterodimer that belongs to the peptidase C14A family of enzymes. It is widely expressed and considered to be the major executioner caspase in the apoptotic cascade. Human procaspase-3 is a 32 kDa, 277 amino acid (aa) protein and is normally an inactive homodimer. Following cell stress/activation, procaspase-3 undergoes proteolysis to generate an N-terminal 148 aa p17/17 kDa subunit (aa 29-175), plus a 102 aa C-terminal p12/12 kDa subunit. These subunits noncovalently heterodimerize, and associate with another p17/p12 heterodimer to form an active enzyme. There is one potential variant that shows an alternative start site nine aa upstream of the standard start site coupled with a 21 aa substitution for aa 162-277. Over aa 29-175, human and mouse caspase-3 share 87% aa identity.
