Background Information

PARP1 (poly(ADP-ribose) polymerase 1) is a nuclear enzyme catalyzing the poly(ADP-ribosyl)ation of many key proteins in vivo. The normal function of PARP1 is the routine repair of DNA damage. Activated by DNA strand breaks, the PARP1 is cleaved into an 85 to 89-kDa COOH-terminal fragment and a 24-kDa NH2-terminal peptide by caspases during the apoptotic process. The appearance of PARP fragments is commonly considered as an important biomarker of apoptosis. In addition to caspases, other proteases like calpains, cathepsins, granzymes and matrix metalloproteinases (MMPs) have also been reported to cleave PARP1 and gave rise to fragments ranging from 42-89-kDa. This antibody was generated against the C-terminal region of human PARP1 and it recognizes the full-length as well as the cleavage of the PARP1.

K. (Verified Customer) (10-26-2023)

this antibody worked well, but some times we need to add it at high concentrations

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:500
  • Cell Tissue Type: Human Liver cells

Priscila (Verified Customer) (04-25-2023)

Very clean detection on western blotting. Sharp bands, and the p89 proteolytic fragment of PARP1 is detectable (tested conditions: 25µg of protein lysate and 1:2,500 dilution for endogenous PARP1 in HEK293T cells).

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:2,500

Ruchi (Verified Customer) (12-09-2022)

The Ab was used for IF at a dilution of 1:100 for staining mice skin wounds. This is a nuclear protein and so required an additional time for fixation (30 minutes in 4% paraformaldehyde) and permeabilization by chilled methanol for 10 minutes. The blocking buffer used was 4% BSA.

  • Applications: Immunofluorescence
  • Primary Antibody Dilution: PARP1
  • Cell Tissue Type: Mouse skin

Marina (Verified Customer) (05-30-2022)

In the blot we could detect native PARP1 as well as its cleaved 89 kDa form after PARP inhibitor treatment
