特異性:Recognizes poly (ADP-ribose) polymerase 1 (PARP-1), a ~116kD nuclear enzyme cleaved during apoptosis. PARP-1, a caretaker enzyme, is involved in DNA damage repair, plays roles in diabetes pathophysiology and tumor proliferation.). As well as protecting cells from genomic instability, PARP-1 is involved in the development of both inflammatory and immune responses, and cell death by apoptosis and necrosis. Targets PARP-1, an enzyme which represents a promising target for new developments in therapeutic treatment of immune mediated diseases. PARP-1 has considerable potential for delivering selective tumor cell killing while sparing normal cells.
