Claim:
1. A method for diagnosing prostate cancer in a test subject, comprising: a) obtaining a blood sample comprising cancer cells of epithelial origin from the test subject; b) contacting the cancer cells of epithelial origin with an anti-STEAP1 antibody that specifically binds to the STEAP1 prostate-specific marker with a K c) detecting whether STEAP1 is present on the cancer cells of epithelial origin by contacting the blood sample with an antibody that specifically binds to the STEAP1 prostate-specific marker antibody and detecting binding between STEAP1 and the antibody that specifically binds to the STEAP1 prostate-specific marker; and d) diagnosing the patient with prostate cancer when the presence of STEAP1 on the cancer cells of epithelial origin is detected; wherein the anti-STEAP-1 antibody is 15A5, produced by a hybridoma cell having a microorganism deposit number of PTA-12259, and wherein the detecting is by a method based on immunofluorescent microscopy, flow cytometry, fiber-optic scanning cytometry, or laser scanning cytometry.
