Technical Data
PARP (Poly ADP-Ribose Polymerase)
Poly ADP-Ribose Polymerase (PARP) uses nicotinamide adenine dinucleotide (oxidized form) NAD as a substrate to catalyse the transfer of ADP-ribose to a variety of nuclear protein acceptors. Proteolysis of PARP to its stable 85kD fragment is an early marker of programmed cell death (apoptosis) and is mediated by the caspase CPP32 protein. Cleavage occurs between Adp216 and Gly217, a site in PARP conserved across species.

MW of Antigen: 116kD

Epitope: N-terminal

Applications and Recommended Dilutions:
Western Blotting (Ab 5-10ug/ml for 2hrs at RT)
Immunohistochemistry (Formalin/paraffin only) (Use Ab at 6.25-12.5ug/ml for 30 min at RT) * [Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min.] The optimal dilution for a specific application should be determined by the investigator.

Positive Control: Raji cells. Tonsil

Cellular Localization: Nuclear

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at-20C or colder. Aliquots are stable for at least 12 months at-20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
