Name: Rabbit anti-human Poly (ADP-Ribose) Polymerase 1 Antibody (Polyclonal)
Description and aplications: PARP (EC 22.214.171.124) is a nuclear protein with a molecular mass of 116 kDa and two zinc finger motifs which binds to DNA and specifically detects DNA nicks and breaks produced by different genotoxic agents. PARP catalises the ADP-ribosylation of proteins using NAD+ as a substrate. PARP activation is a consequence of ischemic injury and leads to intracellular depletion of NAD+, which can only be replaced by ATP consumption. Ischemia/Reperfusion (I/R) injury results in substantial DNA damage and cells need to consume large amounts of ATP to
sustain reparative poly-ADP-ribosylation. Proteolysis of PARP to its stable 85-kDa fragment is an early marker of programmed cell death (apoptosis), mediated by caspase 3 or CPP32. Cleavage occurs between Adp216 and Gly217, a site in PARP conserved across species. This antibody reacts with human, mouse and rat PARP.
