Applications Key:
W=Western Blotting
IC=Immunocytochemistry
Reactivity Key:
R=Rat
Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Cleaved PARP (Asp214) Antibody (Rat Specific) detects endogenous levels of the large fragment of rat PARP1 (89 kDa) resulting from caspase cleavage. The antibody does not recognize full length PARP1 or other PARP isoforms.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to carboxy-terminal residues surrounding Asp214 in rat PARP. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of C6 cells, untreated or staurosporine-treated (1 µM), using Cleaved PARP (Asp214) Antibody (Rat Specific).
Background
PARP, a 116 kDa nuclear poly (ADP-ribose) polymerase, appears to be involved in DNA repair in response to environmental stress (1). This protein can be cleaved by many ICE-like caspases in vitro (2,3) and is one of the main cleavage targets of caspase-3 in vivo (4,5). In human PARP, the cleavage occurs between Asp214 and Gly215, which separates the PARP amino-terminal DNA binding domain (24 kDa) from the carboxy-terminal catalytic domain (89 kDa) (2,4). PARP helps cells to maintain their viability; cleavage of PARP facilitates cellular disassembly and serves as a marker of cells undergoing apoptosis (6).
