A method for assaying a body sample for an indicant of exposure to a carcinogen or for an indicant of cancer, prior to the manifestation of clinical symptoms of cancer comprising: (a) contacting said body sample with a receptor molecule, wherein said receptor binds to both (i) a protein ligand and (ii) a peptide having an amino acid residue sequence containing about 7 to about 40 amino acids corresponding to a portion of said protein, and, (b) determining the level of such protein in said body sample by detection of the amount, if any, of protein/receptor complex; wherein an elevated level of said protein, relative of said level in a normal sample, is indicative of exposure of said body sample to a carcinogen. |
