This PARP-1 N-terminal antibody was raised against a His-Tagged fusion protein corresponding to the N-terminal half of human PARP-1 was used to generate this PARP-1 antibody.


Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic. For your convenience, an IgG version (Catalog No. 61639) of this antibody that was purified by Protein A Chromatography is also available.


PARP-1 N-terminal antibody tested by ChIP analysis.
Chromatin IP performed with chromatin from 3T3 cells using 8 µl of PARP-1 N-terminal antibody or rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primer pair specific for the PPARG2 gene. Data are presented as percent of input from cells with a PARP-1 knock-down (black bars) or a control knock-down (gray bars).

PARP-1 N-terminal antibody tested by Western blot.
HeLa cell nuclear extract (20 µg per lane) was probed with PARP-1 N-terminal antibody at a dilution of 1:20,000.


PARP-1 N-terminal (ADPRT) encodes a chromatin-associated enzyme, poly(ADP-ribosyl)transferase, that 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. It also plays a role in the regulation of the molecular events involved in the recovery of cells from DNA damage. Cleavage of PARP-1 (ADPRT) occurs following caspase activation during apoptosis.
