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

This Mouse monoclonal primary antibody from Antibodies.com targets Cancer Antigen 15-3 (CA 15-3), also known as MUC1, a type I transmembrane glycoprotein widely used as a circulating tumor marker in breast carcinoma monitoring. The reagent is supplied at 1 mg and is offered as an ion exchange purified, unconjugated IgG1 preparation (clone IN266) raised against purified native MUC1, making it well suited for use as either a capture or detection reagent in sandwich immunoassays. Validated applications include ELISA (capture at 2–8 µg/mL, detection at 0.5–2.0 µg/mL), Western blot (WB), and immunohistochemistry (IHC), with reactivity confirmed against human samples. The antibody should be stored according to standard monoclonal antibody conditions, typically aliquoted and kept at –20 °C in working aliquots to avoid repeated freeze/thaw cycles, with long-term storage at –80 °C recommended for the stock solution. Researchers studying CA15-3/MUC1 expression in epithelial tissues and tumor specimens can pair it with the matching IN265 clone (DMABP-L02) for optimized sandwich ELISA performance, and the unconjugated format allows downstream conjugation to fluorophores, biotin, or enzymes as required by the experimental workflow.
