CA 15-3 - mouse clone DF3

This antibody has been used for evaluating the primary site of a metastatic carcinoma of unknown origin and distinguishing between benign and malignant lesions. It is believed that CA15-3 reacts primarily with the DF3-antigen, a 300 kDa mucin-like glycoprotein present on the apical border of secretory mammary epithelial cells. CA15-3 has been detected with immunohistochemistry in a wide spectrum of carcinomas, including Breast Carcinomas (ductal and lobular), Sarcomas (Synovial Sarcoma and Malignant Fibrous Histiocytomas), and Lung Carcinomas. CA15-3 can be used as a supplementary marker for epithelial differentiation. CA15-3 does not stain Melanomas or Ewing’s Sarcomas. Approximately 30% of Hepatocellular Carcinomas are positive for CA15-3.

Available options include prediluted (3ml, 7 ml, 15ml), concentrate (0.1 ml, 0.5ml, 1ml) and 5+ control slides.
