Reported/annotated localization context: Nuclear. Species reactivity (as provided): Human.

Key elements and design rationale

• Target: P63 — selectivity and interpretation should be considered in the context of isoforms, post-translational modifications, and related family members when applicable.
• Format: Purified — format can influence background, multiplexing compatibility, and downstream detection strategies.
• Antibody identity: Mouse, Monoclonal (mouse origin), clone TP63/1786, isotype Mouse IgG2b, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
• Localization: Nuclear — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
• Product notes (from provided description): p63 is a homolog of the tumor suppressor p53. It is identified in basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium, breast and prostate. p63 was detected in nuclei of the basal epithelium in normal prostate glands; however, it was not expressed in malignant tumors of the prostate. As a result, p63 has been reported as a useful marker for differentiating benign from malignant lesions in the prostate, particularly when used in combination with markers of high molecular weight cytokeratins and the prostate-specific marker AMACR (P504S). p63 has also been shown to be a sensitive marker for lung squamous cell carcinomas (SqCC), with a sensitivity of ~90%. Specificity for lung SqCC, vs. lung adenocarcinoma (LADC), is approximately 80%. In breast tissue, p63 has been identified in myoepithelial cells of normal ducts.

Where multiple assay formats are possible, align the antibody format, host/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.

Biological background

In this catalog, P63 is positioned within Oncology & Angiogenesis, Tumor research contexts. Localization annotations (e.g., Nuclear) can help contextualize expected signal patterns in imaging and fractionation-based readouts. For authoritative gene/protein nomenclature, domains/isoforms, and curated functional annotations, consult resources such as UniProt, NCBI Gene, and Ensembl.

Research relevance and current trends

• Higher-plex and spatially resolved readouts (e.g., multiplex IF/IHC, spatial omics) are increasing demand for well-characterized primary antibodies with clearly stated host/isotype and labeling strategies.
• Genetic perturbation controls (knockout/knockdown) and orthogonal measurements (e.g., RNA vs protein) are commonly used to strengthen target attribution when interpreting antibody-derived signals.
• Reproducibility initiatives emphasize transparent reporting of antibody identity (clone, host, isotype) and experimental context to improve cross-study comparability.

Common research applications

• ELISA: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• WB: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Typical workflow themes: Western blot validation, ELISA binding assay, Specificity controls.
• Workflow notes: Validate P63 by Western blot in cell/tissue lysates (include controls), Measure binding to P63 peptide/protein by ELISA with dilution series (include blanks), Confirm specificity using KO/KD or peptide competition con…

When comparing conditions, consistent sample processing and appropriate negative/positive controls support interpretation of qualitative localization differences and quantitative abundance changes.

Notes for experimental interpretation

• Isoforms and post-translational modifications may shift apparent molecular weight or epitope accessibility, especially across cell states or treatments.
• Species and tissue context can affect sequence conservation, expression level, and background binding; predicted reactivity should be verified in your sample.
• Control concepts include isotype-matched controls, secondary-only controls (for indirect detection), and genetic/orthogonal controls (e.g., KO/KD, independent antibodies, or RNA measurements) when feasible.

Monoclonal and polyclonal antibodies can differ in epitope recognition breadth and lot-to-lot characteristics; consider clonality and clone information (when provided) alongside your assay requirements. Conjugated formats may simplify detection but can change background and multiplexing behavior compared with unconjugated primaries.
