Technical Data
PARP (Poly ADP-Ribose Polymerase) (BSA & Azide Free)
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.

Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Western Blot: 5-10ug/ml for 2hrs at RT
Immunohistochemistry (Formalin/paraffin only): 6.25-12.5ug/ml for 30 min at RT. Requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min.
Optimal dilutions to be determined by the researcher.

Recommended Positive Control:
Raji cells, Tonsil

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. 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.
