PARP Cleavage Site, p85, Asp214/Gly215 (Poly ADP-Ribose Polymerase)
Description:
Poly (ADP-ribose) polymerase (PARP) is zinc-dependent DNA binding protein that recognizes DNA strand breaks and is presumed to play a role in DNA repair (1). As a marker for apoptosis, PARP is cleaved in vitro by many caspases, and in vivo by Caspase-3 (2,3). Existing as a 116kD nuclear protein, PARP is cleaved between amino acids Asp214 and Gly215 to yield two fragments of 29kD and 85kD (2,4).

Applications:
Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 1:50
Western Blot: 1:1,000
Immunocytochemistry: 1:50
Immunoprecipitation: 1:50

Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Freeze at -20°C. Aliquots are stable for at least 12 months at -20°C. 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.

Manufactured incorporating RabMAb® technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
