Patent ID: 7754435

Claim:
A method of diagnosing prostate cancer in a mammal, said method comprising obtaining a biological sample from said mammal, assessing the level of antibody that specifically binds with PCADM-1 in said biological sample, and comparing the level of antibody that specifically binds with PCADM-1 in said biological sample with the level of antibody that specifically binds with PCADM-1 in a biological sample obtained from a like mammal not afflicted with prostate cancer, wherein a higher level of antibody that specifically binds with PCADM-1 in said biological sample from said mammal compared with the level of antibody that specifically binds with PCADM-1 in said biological sample from said like mammal is an indication that said mammal is afflicted with prostate cancer, thereby diagnosing prostate cancer in a mammal, wherein the sequence of PCADM-1 comprises the sequence set forth in SEQ ID NO:2, and wherein said antibody does not crossreact non-specifically with human S2 ribosomal protein.
