Overview
Annexin A1 Antibody is a research-use primary antibody intended for detection of ANNEXIN in experimental workflows. It is supplied in Purified format. Key antibody attributes include Mouse, Monoclonal (mouse origin), clone ANXA1/1672, isotype Mouse IgG1, kappa. Applications listed for this product include FACS, ELISA, WB. Reported/annotated localization context: Nuclear and Cytoplasmic. Species reactivity (as provided): Human.
Key elements and design rationale
- Target: ANNEXIN (Annexin A1) — 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 ANXA1/1672, isotype Mouse IgG1, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
- Localization: Nuclear and Cytoplasmic — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
- Product notes (from provided description): The ANXA1 gene belongs to the annexin family, and contains 4 annexin repeats. A pair of annexin repeats may form one binding site for calcium and a phospholipid. ANXA1 promotes membrane fusion and is involved in exocytosis. The gene for ANXA1 is upregulated in hairy cell leukemia (HCL), and its protein expression is specific for HCL. Detection of ANXA1 provides a simple, highly sensitive and specific assay for diagnosing HCL. Annexin A1 has also been found to be protective against DNA damage induced by heat in breast cancer cells, suggesting it is involved in tumor suppressive and protective activities, and also is associated with treatment resistance.
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, ANNEXIN is positioned within Molecular & Cellular Biology, Cancer, Tumor, Leukemia research contexts. Localization annotations (e.g., Nuclear and Cytoplasmic) 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
- FACS: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
- 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, Flow cytometry staining, ELISA binding assay, Specificity controls.
- Workflow notes: Validate ANNEXINA1 by Western blot in cell/tissue lysates (include controls), Quantify ANNEXINA1-positive cells by flow cytometry in single-cell suspensions (include viability gate), Measure binding to ANNEXINA1 pepti…
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.
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).
