Rabbit Monoclonal antibody [E78] to PARP (p116/p85)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 . As a marker for apoptosis, PARP is cleaved in vitro by many caspases, and in vivo by Caspase-3 . Existing as a 116 kDa nuclear protein, PARP is cleaved between amino acids Asp214 and Gly215 to yield two fragments of 29 kDa (C-terminal catalytic domain) and 85 kDa (N-terminal DNA-binding domain) .
Immunogen
A synthetic peptide corresponding to residues near to C-terminal residues of human PARP-1 was used as immunogen.
