Characterization of the human tumor and normal tissue reactivity of the KS1/4 monoclonal antibody

Hybridoma. 1988 Aug;7(4):407-15. doi: 10.1089/hyb.1988.7.407.


The tissue and tumor distribution of the antigen recognized by monoclonal antibody KS1/4 was determined by a combination of immunoperoxidase techniques, flow cytometric analyses and solid phase enzyme-linked immunoassays. These data document that the KS1/4 antigen is expressed in many epithelial malignancies and normal epithelial surfaces suggesting that this antigen represents an epithelial/epithelial malignancy marker.
