Poly (ADP-ribose) polymerase (PARP) is zinc-dependent DNA binding protein that recognizes DNA strand breaks and is presumed to play a role in DNA repair (1). As a marker for apoptosis, PARP is cleaved in vitro by many caspases, and in vivo by Caspase-3 (2,3). Existing as a 116 kDa nuclear protein, PARP is cleaved between amino acids Asp214 and Gly215 to yield two fragments of 29 kDa and 85 kDa (2, 4).
Flow Cytometry: PARP-1 (Cleaved p85) Antibody (Y34) [NB110-57321] - Analysis of apoptotic and non-apoptotic Jurkat cells using anti-cleaved PARP-1. Jurkat cells were either left untreated (A) or treated with camptothecin (4 uM, 5 hr) to induce apoptosis (B). Cells were fixed and permeabilized, and then stained with anti-cleaved PARP-1. The results indicate that 43% of cells were positive for cleaved PARP (B, M2) after treatment, compared to 9% positive without treatment (A, M2).
