Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

PARG (D4E6X) Rabbit mAb recognizes endogenous levels of total PARG protein. This antibody specifically recognizes PARG isoform 1 (UniProt #Q86W56-1) and does not recognize other PARG isoforms.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human PARG protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from HPB-ALL, HeLa, and COS-7 cells using PARG (D4E6X) Rabbit mAb.



Immunoprecipitation of PARG from HPB-ALL cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is PARG (D4E6X) Rabbit mAb. Western blot analysis was performed using PARG (D4E6X) Rabbit mAb.


Poly (ADP-ribose) glycohydrolase (PARG) is an enzyme that hydrolyzes poly (ADP-ribose) (PAR) formed by members of the PAR polymerase (PARP) enzyme family. Poly (ADP)-ribosylation is a post-translational modification that is catalyzed by PARP proteins. This modification involves polymerization of ADP-ribose from NAD+ to target proteins, such as histones and transcription factors, and plays a wide range of biological roles, including the response to DNA damage and transcriptional regulation (1,2). The mammalian PARG enzyme that catalyzes the removal of this modification exists as multiple isoforms. Longer PARG isoforms (100-110 kDa) shuttle between the nucleus and cytoplasm and are responsible for most of the PARG activity. The smaller (65 kDa) isoform resides in the cytoplasm (3-5). Research studies link altered PAR metabolism to inflammatory and autoimmune diseases, as well as neuronal degeneration (6-8). PARG inhibitors that increase PAR levels may sensitize cells to cancer treatments (e.g., cisplatin) and may help in the development of cancer therapies (9).
