DescriptionRabbit polyclonal to Cleaved PARP1
SpecificityThis antibody specifically recognizes the 85 kDa fragment of cleaved PARP1 and can be used as marker for detecting apoptotic cells. Cleavage site specific antibody, unconjugated. The antiserum was produced against a chemically synthesized peptide corresponding to the N-terminus of cleavage site (214/215) of human PARP1 and will recognize Asp 214 and Gly 215.

PurityImmunogen affinity purified
Purification notesPurified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a peptide spanning the cleavage site to remove antibody that is reactive with full length PARP1. The final product is generated by affinity chromatography using a peptide corresponding to the PARP1 cleavage site.

FunctionInvolved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. With EEF1A1 and TXK, forms a complex that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production. Required for PARP9 and DTX3L recruitment to DNA damage sites. PARP1-dependent PARP9-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites.

Proteins from cell extracts were resolved by SDS-PAGE on a 4-20% Tris glycine gel and were transferred to PVDF membrane. Membranes were incubated with either 1 µg/mL anti-PARP1 (pan) antibody or anti-PARP1 cleavage site (214/215) specific antibody at 1 µg/mL. After washing, membranes were incubated with goat F(ab’)2 antirabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar detection method. The data show that the anti-PARP1 cleavage site specific antibody only recognizes the 85 kDa fragment of PARP1 in apoptotic cells (lane 3) and does not react with full length PARP1 (lane 1). The PARP1 (pan) antibody confirms that nonapoptotic cells express full length PARP1 of 116 kDa (lane 2) and which is cleaved when apoptosis is induced (lane 4).
HeLa cells were induced into apoptosis with staurosporine at 0.5 µM for 5 hours (panel A) and were untreated as control (panel B). The cells were fixed in cold acetone for 5 minutes. Cells were incubated with the anti-PARP1 cleavage site specific antibody (CCSA) at 10 µg/mL. Cells were then incubated with biotinylated goat anti-rabbit Igs followed by ABC and DAB. The data show that the anti-PARP1 CCSA specifically recognizes PARP1 in apoptotic cells. Taken together with Western blot data above, these data demonstrate the specificity of the anti-PARP1 CCSA for cleaved PARP1.
