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

This Mouse monoclonal IgG1 antibody from Antibodies.com targets Cancer Antigen 15-3 (CA 15-3), a tumor-associated MUC1 glycoprotein routinely monitored in breast cancer patient management. The reagent is supplied as an ion exchange purified preparation at 1 mg per vial in unconjugated format, giving researchers full flexibility to attach biotin, fluorophores, or enzymes for their own detection chemistry.

Validated for ELISA, western blot (WB), and immunohistochemistry (IHC), the antibody supports quantitative antigen assays, confirmatory membrane-based protein detection, and tissue localization on formalin-fixed sections. The murine host and IgG1 isotype integrate cleanly with common anti-mouse secondary antibodies, HRP conjugates, and fluorescent detection systems used across routine research workflows. For research use only.

For handling, aliquot upon arrival to limit repeated freeze-thaw cycles and refrigerate the working stock; for long-term storage, keep frozen at -20°C in single-use aliquots to preserve binding affinity. The unconjugated format also supports affinity purification and immunoprecipitation workflows, where native antibody-binding activity is required without an attached reporter molecule.
