Cancer Antigen 125 (CA 125) Antigen ≥95%

For diagnostic assay developers working with the CA 125 / MUC16 ovarian cancer biomarker, this Liquid-format antigen preparation from Antibodies.com delivers ≥95% purity at 10 kU per unit, validated for both ELISA and Western Blot (WB) workflows. CA 125, also known as MUC16, is a heavily glycosylated transmembrane mucin recognized as a clinically important tumor marker, particularly for monitoring epithelial ovarian carcinoma. Researchers developing calibrator standards, antibody screening panels, and immunoassay positive controls can incorporate this antigen to standardize detection of the MUC16 epitope across experiments. The Liquid form is convenient for direct dilution into coating buffers for plate-based detection systems, while the defined purity specification supports reproducible analytical sensitivity benchmarking between runs. For optimal stability, the antigen should be stored frozen in single-use aliquots to limit repeated freeze-thaw cycles and preserve antigenic activity over time.
