Applications: Suitable for use with BPS's assay kits to screen for inhibitors of PARPs 1, 2, 3, and 6, or for activating PARP-1 or PARP-2 enzymes in vitro.
Background: PARP is found in the cell's nucleus. The main role is to detect and signal single-strand DNA breaks (SSB) to the enzymatic machinery involved in the SSB repair. PARP activation is an immediate cellular response to metabolic, chemical, or radiation-induced DNA SSB damage. Once PARP detects a SSB, it binds to the DNA, and, after a structural change, begins the synthesis of a poly (ADP-ribose) chain (PAR) as a signal for the other DNA-repairing enzymes such as DNA ligase III (LigIII), DNA polymerase beta (pol?), and scaffolding proteins such as X-ray cross-complementing gene 1 (XRCC1). After repairing, the PAR chains are degraded via Poly(ADP-ribose) glycohydrolase (PARG). Both PARP-1 and PARP-2 are activated by DNA single-strand breaks.
Description: Activated DNA for PARP assay, for use with BPS's assay kits for PARPs 1, 2, 3, and 6.
