Biological background

ERCC1 (protein: T-cell surface glycoprotein CD4) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Isoform 1: Non-catalytic component of a structure- specific DNA repair endonuclease responsible for the 5'-incision during DNA repair. Responsible, in conjunction with SLX4, for the first step in the repair of interstrand cross-links (ICL). Participates in the processing of anaphase bridge-generating DNA structures, which consist in incompletely processed DNA lesions arising during S or G2 phase, and can result in cytokinesis failure. Also required for homology-ed repair (HDR) of DNA double-strand breaks, in conjunction with SLX4. Reported cellular localization context: Isoform 1: Nucleus. Tissue expression notes (as provided): Calprotectin (S100A8/9) is predominantly expressed in myeloid cells. Except for inflammatory conditions, the expression is restricted to a specific stage of myeloid differentiation since both proteins are expressed in circulating neutrophils and monocytes but are absent in normal tissue macrophages and lymphocytes. Under chronic inflammatory conditions, such as psoriasis and malignant disorders, also expressed in the epidermis. Found in high concentrations at local sites of inflammation or in the serum of patients with inflammatory diseases such as rheumatoid, cystic fibrosis, inflammatory bowel disease, Crohn's disease, giant cell arteritis, cystic fibrosis, Sjogren's syndrome, systemic lupus erythematosus, and progressive systemic sclerosis. Involved in the formation and deposition of amyloids in the aging prostate known as corpora amylacea inclusions. Strongly up-regulated in many tumors, including gastric, esophageal, colon, pancreatic, bladder, ovarian, thyroid, breast and skin cancers. .

Research relevance and current trends

• Research context keywords from the source record include: Cancer,DNA/RNA,DNA Damage & Repair,Epigenetics and Nuclear Signaling,Tumor Biomarkers.
• Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
• Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.

Common research applications

• Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.

Workflow ideas (metafield): Validate ERCC1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect ERCC1 expression by Western blot in cell or tissue lysates, Detect ERCC1 in FFPE tissue sections by immunohistochemistry, Localize ERCC1 by immunofluorescence/immunocytochemistry in cultured cells

Notes for experimental interpretation

• Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
• Apparent molecular weight may vary by sample type and processing (observed MW: 125 kDa; calculated MW: 32562 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
