Patent ID: 7534575

Claim:
A method for detecting a cancer, in which Zcytor16 is expressed in tumor tissue but is not expressed in normal tissue, in a patient, comprising: obtaining a tissue or biological sample from the patient; incubating the tissue or biological sample with an antibody or antibody fragment under conditions wherein the antibody or antibody fragment specifically binds to a polypeptide in the tissue or biological sample, wherein the polypeptide in the tissue or biological sample consists of an amino acid sequence selected from the group consisting of: (a) amino acid residues 21 to 231 of SEQ ID NO:2, and (b) amino acid residues 22 to 231 of SEQ ID NO:2; visualizing the antibody bound in the tissue or biological sample; and comparing levels of antibody bound in the tissue or biological sample from the patient to a normal control tissue or biological sample, wherein an increase in the level of antibody bound to the patient tissue or biological sample relative to the normal control tissue or biological sample is indicative of a cancer in the patient.
