Human Carbohydrate Antigen 15-3 (CA15-3) ELISA Kit

The Human Carbohydrate Antigen 15-3 (CA15-3) ELISA Kit from Assay Genie is a quantitative in vitro immunoassay that measures the CA15-3 mucin-like glycoprotein, a circulating tumor marker most commonly elevated in patients with breast cancer.

CA15-3 concentrations are routinely tracked to evaluate therapeutic response, detect recurrence, and assist prognosis in metastatic disease, with rising values often correlating with tumor burden.

Researchers apply this research-use-only kit to oncology investigations, biomarker validation, and longitudinal studies of breast carcinoma, where serial measurements help monitor treatment efficacy and early relapse.
