Human CA125

The Human CA125 protein offered by Antibodies.com is a recombinant preparation of MUC16, a heavily glycosylated mucin-type transmembrane glycoprotein widely studied as the canonical serological biomarker for epithelial ovarian carcinoma. This unconjugated liquid reagent is supplied at 1 mg and is intended for research use only, supporting method development in cancer antigen quantification, monoclonal antibody characterisation, and epithelial tumor biology investigations.

Suitable downstream applications include ELISA standard curve generation, Western blot validation, immunohistochemistry calibration, and flow cytometry reference work, where the full-length extracellular repeat architecture provides authentic epitope presentation. To preserve activity and shelf life, the protein should be stored frozen in single-use aliquots, with repeated freeze-thaw cycles avoided to prevent degradation of the mucin domain.
