Product Overview
This rabbit polyclonal antibody recognizes hepatocyte nuclear factor 3-alpha (gene FOXA1) in human samples and is validated for ELISA, flow cytometry and Western blot. The predicted molecular weight is 49.1 kDa, and the supplier reports an observed band at about 49 kDa.
FOXA1 (HNF-3α) is a forkhead transcription factor that acts as a pioneer factor: it can bind compacted chromatin and open it so other transcription factors can reach their targets. It is important in development of the liver, pancreas, lung and prostate and guides estrogen and androgen receptor binding in breast and prostate cancer.

|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human MCF-7 cells, human HepG2 cells, human RT4 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with a confirmed signal (flow cytometry): RT4 cells.
Immunogen
Recombinant human FOXA1 fragment (Met1–Thr55), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places hepatocyte nuclear factor 3-alpha in the nucleus. Tissue expression noted by UniProt (human): Highly expressed in prostate and ESR1-positive breast tumors. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
