<p>The present invention provides a novel complex of hK2 and PI-6 and methods of using the novel complex. The novel complexes of hK2 and PI-6 of the present invention exist at an elevated level in prostat cancer tissues. Therefore, the hK2-PI6 complexes of the present invention may be used as a serum marker for detecting prostate cancer. They may also be used as an immunohistological marker to detect prostate cancer tissues. In accordance with the present invention, the hK2-PI6 complexes of the present invention may be detected in patient tissue samples by immunohistochemical and/or in patient fluid samples by in vitro immunoassay procedures. Diagnostic kits and diagnostic methods for detecting the existence of prostate cancer are also provided.</p> |
