Anti-Cancer Antigen 15-3 (CA 15-3) MUC 1 Antibody

Mouse monoclonal IgG1 antibody supplied by Antibodies.com targets the MUC1 mucin glycoprotein, recognizing the Cancer Antigen 15-3 (CA 15-3) epitope widely studied as a tumor-associated marker in breast carcinoma research. The reagent is provided as an ion exchange purified preparation at 1 mg per vial, unconjugated so it can be deployed directly or custom-labeled for laboratory workflows.

Validated applications include ELISA, Western blot (WB), and immunohistochemistry (IHC), enabling detection of the MUC1 tandem-repeat region in cell lysates, formalin-fixed tissue sections, and conditioned media. Researchers examining epithelial mucin overexpression, tumor marker panels, or epithelial-mesenchymal transition studies can pair this reagent with standard anti-mouse secondary antibodies for chromogenic, chemiluminescent, or fluorescent readouts. The IgG1 isotype works with commonly used HRP, biotin, and Alexa Fluor conjugates.

Storage recommendations: refrigerate upon arrival; for long-term use, aliquot the contents of each vial and freeze to limit freeze-thaw cycles. The unconjugated format gives flexibility for in-house biotinylation, fluorophore conjugation, or direct use in standard immunostaining protocols across cancer biomarker research programs.
