ABSTRACT:
This invention provides a method of imaging a colorectal carcinoma lesion in a human patient which comprises administering to the patient a monoclonal antibody capable of binding to a cell surface antigen associated with the colorectal carcinoma lesion and which is labeled with an imaging agent under conditions so as to form a complex between the monoclonal antibody and the cell surface antigen, imaging any complex so formed, and thereby imaging the colorectal carcinoma lesion.
This invention also provides a monoclonal antibody designated AS 33 (ATCC Accession No. HB 8779) and the hybridoma which produces it.
