Human PARP 1 Enzyme, High Specific Activity

High specific activity PARP1 (PARP-HSA) is used in Trevigen’s PARP Assay Kits. The specific activity serves as a measure of enzyme purity, with greater than 95% purity for PARP-HSA. PARP1 is activated by 10X Activated DNA, which can be assayed using Trevigen’s Universal or PARP/Apoptosis Assay Kits.

Available Size(s): 1,000 units, 20,000 units, 5,000 units Catalog Number: 4668-02K-01 Category:


10 units/µl
Purified from E.  coli containing a recombinant plasmid harboring human PARP1 gene.
PARP1 uses NAD+ as a substrate to catalyze poly(ADP-ribosyl)ation of target proteins involved  in  chromatin  structure  and  DNA  metabolism. PARP1 is stimulated by DNA-strand breaks and capable of auto-ribosylation.
Store at -20°C in a manual defrost freezer. For long-term storage, freeze at -80°C in working aliquots.
