PARP, Cleavage Site (Asp214) (Poly ADP-Ribose Polymerase)
Description:
PARP, a 116kD nuclear poly (ADPribose) polymerase, appears to be involved in DNA repair predominantly in response to environmental stress (1). This protein can be cleaved by many ICElike caspases in vitro (2,3) and is one of the main cleavage targets of caspase-3 in vivo (4,5). In human PARP the cleavage occurs between Asp214 and Gly215, which separates PARPs N-terminal DNA binding domain (24kD) from its C-terminal catalytic domain (89kD) (2,4). PARP is important for cells to maintain their viability; cleavage of PARP facilitates cellular disassembly and serves as a marker of cells undergoing apoptosis (6).

Applications:
Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunofluorescence and Flow Cytometry. Other applications have not been tested.

Recommended Dilution:
Western Blot: 1:1000
Immunohistochemistry (Paraffin): 1:50
Immunocytochemistry (IF): 1:200
Flow Cytometry: 1:25

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
