The total weight can be determined using the Unit Activity and the Protein Concentration reported on the lot specific Certificate of Analysis. For example, for the 1KU pack size, if the activity is 10 units/µl and the protein concentration is 0.384 mg/ml the weight would be 0.26mg.

General description
Application
PARP-1 is a nuclear enzyme that synthesizes ADP-ribose polymers from NAD+, specifically binds Zn2+ and DNA, and recognizes single-strand breaks in DNA. PARP1 has been used in a study to assess racial and tissue-specific cancer risk associated with polymorphism in the PARP1 gene. It has also been used in a study to investigate inhibitors of PARP-1 for potential cancer treatments.
PARP-1 human has been used in the GST-pull down assay for immunoprecipitation of Glutathione S-transferase (GST) or GST- cyclic GMP- AMP synthase (cGAS) (GST-cGAS). It has also been used in in vitro ribosylation assay.
Biochem/physiol Actions
PARP-1 is inactivated by cleavage into a 24kDA and 89kDA fragment by activated caspase-3 or caspase-7. This results in the decreased ability to repair DNA damage and an increase in apoptosis.
Poly(ADP-ribose) polymerase 1 (PARP1) is essential for diverse functions like DNA damage detection and repair, chromatin modification, cell differentiation, transcription and apoptotic cell death. It also plays a major role in spermatogenesis. Polymorphism in the gene PARP1 is associated with oligospermia and causes male infertility.
PARP-1, a nuclear enzyme that synthesizes ADP-ribose polymers from NAD, specifically binds Zn2+ and DNA, and recognizes single-strand breaks in DNA. It is involved in base excision repair, both short-patch and long-patch, rejoining DNA strand breaks and plays a role in p53 expression and activation. A high level of basal neuronal DNA damage and PARP activity has been reported in rat brain tissue. PARP-1 was shown to be required for HIV-1 integration into DNA. If PARP-1 is deficient there is no productive HIV-1 infection.
Physical form
Supplied as a solution in 20 mM Tris-HCl, pH 8.0, 200 mM NaCl, 1 mM DTT, 0.1% Triton™-X 100, 50 % glycerol, and 0.1 mg/ml BSA.
Other Notes
One unit will incorporate 10 femptomole of poly(ADP-ribose) from NAD into 5 μg of immobilized histone proteins in 30 minutes at 22 °C in a 96 well plate.
