PARP1 Automodified is highly purified human PARP1, expressed in a baculovirus expression system, to which NAD+ and cofactors have been added to allow PARP automodification by poly(ADP-ribose). The PARP1 is lyophilized from its native state, and upon reconstitution with water, it retains residual poly ADP-ribosylation enzymatic activity. It is useful as a standard for ELISA, SDS-PAGE, Western blotting, and in other assays. Full-length hPARP1
Poly (ADP-ribose) polymerase-1 (PARP1) is an abundant and ubiquitous nuclear enzyme that catalyzes the NAD(+)-dependent addition of ADP-ribose polymers on a variety of nuclear proteins.
