DETECTION OF PROSTATE CANCER USING PSA GLYCOSYLATION PATTERNS

The present invention features novel methods for determining if a subject has prostate cancer. The present invention is based on the development of lectin immunosorbant assays which analyze α2,6-linked sialylation of total serum PSA by sambucus nigra lectin (SNA) and α2,3-linked sialylation of total...

Zusammenfassung:	The present invention features novel methods for determining if a subject has prostate cancer. The present invention is based on the development of lectin immunosorbant assays which analyze α2,6-linked sialylation of total serum PSA by sambucus nigra lectin (SNA) and α2,3-linked sialylation of total and free serum PSA. These novel assays were used then to conduct a clinical investigation of the potential role of glycoprotein analysis in improving PSA's cancer specificity. The present invention also features kits for determining if a subject has prostate cancer comprising one or more lectins and a PSA specific antibody and instructions for use.
