Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E.coli-derived human PARP recombinant protein (Position: Q670-R858). Human PARP shares 94% and 95% amino acid (aa) sequence identity with mouse and rat PARP, respectively. (reported region: Q670-R858).
• Molecular weight context: reported MW: 120 kDa; calculated MW: 113084 MW
• Reactivity: Human,Mouse,Rat
• Applications: Flow Cytometry, IF, IHC, ICC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

Poly [ADP-ribose] polymerase 1; Poly [ADP-ribose] polymerase 1. Poly [ADP-ribose] polymerase 1 (PARP1), also known as ADPRT or PPOL is an enzyme that in humans is encoded by the PARP1 gene. PARP1 gene is mapped to 1q42.12. This gene encodes a chromatin-associated enzyme, poly (ADP-ribosyl)transferase, which modifies various nuclear proteins by poly (ADP-ribosyl)ation. The modification is dependent on DNA and is involved in the regulation of various important cellular processes such as differentiation, proliferation, and tumor transformation and also in the regulation of the molecular events involved in the recovery of cell from DNA damage. In addition, this enzyme may be the site of mutation in Fanconi anemia, and may participate in the pathophysiology of type I diabetes. Functional note: Involved 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 ly 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. . Reported localization: Nucleus. Nucleus, nucleolus. Localizes at sites of DNA damage. Expression/tissue context: Highly expressed in pancreas, kidney, skeletal muscle, liver, testis and heart. Detected at slightly lower levels in placenta and brain (at protein level). Detected in astrocytes, Sertoli cells, spermatogonia, spermatids and spermatozoa. .

Research relevance and current trends

• Chromatin Modifying Enzymes: Researchers commonly examine how PARP1 (Poly [ADP-ribose] polymerase 1) relates to this theme using model systems and orthogonal readouts.
• Epigenetics and Nuclear Signaling: Researchers commonly examine how PARP1 (Poly [ADP-ribose] polymerase 1) relates to this theme using model systems and orthogonal readouts.

Common research applications

• Western blotting: compare relative PARP1 (Poly [ADP-ribose] polymerase 1) levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of PARP1 (Poly [ADP-ribose] polymerase 1) across tissue regions and cell types using matched controls.
• IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins
• Family / similarity context: Contains 1 BRCT domain.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
