    • The present invention provides a novel complex of hK2 and PI-6 and methods of using the novel complex and its constituents. The novel complexes of hK2 and PI-6 of the present invention and the PI-6 exist at an elevated level in prostate cancer tissues. PI-6 also exists at an elevated level in other types of cancer cells. Therefore, the hK2-PI6 complexes and PI-6 of the present invention may be used as a serum marker for detecting cancers, particularly 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 methods for detecting the existence of prostate cancer is also provided.
    • 本发明提供了hK2和PI-6的新型复合物以及使用该新型复合物及其成分的方法。 本发明的hK2和PI-6和PI-6的新型复合物在前列腺癌组织中的升高水平存在。 其他类型的癌细胞中PI-6也存在于升高的水平。 因此,本发明的hK2-PI6复合物和PI-6可以用作检测癌症,特别是前列腺癌的血清标志物。 它们也可以用作检测前列腺癌组织的免疫组织学标记。 根据本发明,本发明的hK2-PI6复合物可以通过免疫组织化学和/或在患者流体样品中通过体外免疫测定方法在患者组织样品中检测。 还提供了用于检测前列腺癌存在的诊断方法。
