The invention involves monoclonal antibodies which specifically bind to a cell surface antigen characteristic of tumor vascular endothelium. The antigen, referred to as endosialin, is a glycoprotein and has a molecular weight of about 165 kDa as determined by SDS-PAGE. The protein portion of the molecule has a molecular weight of about 95 kDa. Also disclosed are various uses of the monoclonal antibody and the antigen. |
