PARP (ADP-Ribose) Polymerase (PARP) is a 113 kD nuclear protein important for mediating the normal cellular response to DNA damage and repair in response to environmental stress. PARP catalyzes the transfer of ADP-ribose units from NAD⁺ to various nuclear proteins, including topoisomerases, histones, and PARP itself, by poly(ADP-ribosyl)ation. Following DNA damage, this protein is cleaved by ICE-like caspases, such as caspase-3 and -7. In humans, this PARP cleavage occurs between Asp214 and Gly215, yielding an 89 kD (from the carboxy-terminal catalytic domain) and a 24 kD fragment (from the amino-terminal DNA binding domain). PARP is an important regulator of cellular differentiation, proliferation, and tumor transformation, and PARP cleavage is considered a classical characteristic of cells undergoing apoptosis. Additionally, this enzyme may be the site of mutation in Fanconi anemia, and may contribute to the pathophysiology of type I diabetes.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1 - 1.0 µg per ml. For immunocytochemistry, a concentration of 1.0 μg/ml is recommended. For intracellular flow cytometry using our True-Phos™ Perm Buffer in Cell Suspensions Protocol, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
The QA17A17 antibody reacts with the 89 kD (cleaved at Asp214) fragment of human PARP1. It does not react with full-length PARP1.
Fixation and permeabilization using the True-Nuclear Buffer Set and Intracellular Staining Permeabilization Wash Buffer (10X) have also been confirmed to work in addition to the True-Phos™ Perm Buffer during in-house testing and development to detect cleaved PARP (Asp214).
- Additional Product Notes
Clone QA17A17 was tested for ICC using PFA-fixed cells permeabilized with either methanol or Triton X-100. Both methods facilitated strong staining.
