The information above helps you match the antibody format to your assay context, interpret species-dependent differences, and anticipate how epitope context (isoforms, PTMs, or conformational state) may influence signal.

Biological background

XRCC1 (X-ray Repair Complementing Defective in Chinese Hamster 1) is a DNA repair protein which complexes with DNA ligase III. The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. The XRCC1 gene is mapped to 19q13.31. The XRCC1 interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity. XRCC1 is phosphorylated in vivo and in vitro by CK2, and CK2 phosphorylation of XRCC1 on ser518, thr519, and thr523 largely determines aprataxin binding to XRCC1 through its FHA domain.

For curated annotations (gene/protein naming, domains, isoforms, and pathway links) for XRCC1, consult primary databases such as UniProt, NCBI Gene, and Ensembl.

Research relevance and current trends

• Context-dependent expression studies: researchers often examine XRCC1 abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.
• Reagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone/lot information.
• Multi-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.

Common research applications

• Western blotting (immunoblot) for relative detection of target protein abundance and apparent molecular weight.
• Immunohistochemistry for spatial mapping of target expression across tissues and cell types.
• Immunofluorescence for subcellular localization and cell-type specific expression patterns.
• ELISA-based detection or quantification in research assays (format- and epitope-dependent).

When comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.

Notes for experimental interpretation

• Isoforms and PTMs: alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands/signals accordingly.
• Cross-reactivity and matrix effects: background binding can vary by sample type, species, and blocking/detection chemistries; include appropriate negative controls.
• Control concepts: where feasible, use genetic perturbation (KO/KD/overexpression), orthogonal assays, or independent antibodies to support specificity claims.

Antibody considerations: Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments. If a conjugate is listed, the antibody supports more direct detection workflows; otherwise, it is typically used with a compatible secondary antibody.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
