This antibody specifically recognizes the 85 kDa fragment of cleaved PARP and can be used as a marker for detecting apoptotic cells. The antibody has been used in western blotting and previous lots have been used in immunostaining applications. Positive controls used in western blotting were Jurkat or HeLa cells treated with staurosporine or etoposide (25 µM for 3 hours).
Poly (ADP-Ribose) Polymerase (PARP) is a 116 kDa nuclear protein which is strongly activated by binding to DNA strand breaks. PARP is also known as the chromatin-associated enzyme, poly(ADP-ribosyl)transferase, which modifies various nuclear proteins by poly(ADP-ribosyl)ation. The modification is dependent on DNA and is involved in the regulation of various important cellular processes such as differentiation, proliferation, and tumor transformation and also in the regulation of the molecular events involved in DNA replication and the recovery of the cell from DNA damage. During apoptosis, ICE family members, such as caspase-3 and -7, cleave PARP to yield an 85 kDa and a 25 kDa fragment. PARP cleavage is considered to be one of the classical characteristics of apoptosis. In addition, this enzyme may be the site of mutation in Fanconi anemia, and may participate in the pathophysiology of type I diabetes.
