Product Overview
This rabbit polyclonal antibody detects mucin-1 (gene MUC1) in human samples and is validated for Western blot, IHC, ICC/IF and ELISA. The predicted molecular weight is 122.1 kDa, and the supplier reports an observed band at about 25–30 kDa.
Mucin-1 (MUC1) is a heavily glycosylated transmembrane mucin on the apical surface of most epithelia, forming part of the protective barrier. Its cytoplasmic tail engages signaling pathways including ERK, SRC and NF-κB and can influence p53-regulated transcription. MUC1 is often overexpressed and aberrantly glycosylated in carcinomas, so it is widely studied in cancer biology.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human T47D cells， human HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% 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 confirmed staining (IHC): human invasive adenocarcinoma of the lung tissue, human endometrioid adenocarcinom tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): human lung adenocarcinoma tissue.
Immunogen
Recombinant human MUC1 fragment (Thr1063–Arg1131), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places mucin-1 in the apical cell membrane. Tissue expression noted by UniProt (human): Expressed on the apical surface of epithelial cells, especially of airway passages, breast and uterus. 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).
