Prostate-specific antigen (PSA) was purified from human seminal plasma by ion-exchange chromatography and gel filtration. The purified antigen was dialyzed against d.H2O and lyophilized.


Prostate-specific antigen (PSA) is a glycoprotein of approx. 30 kDa found mainly in prostatic tissue and seminal fluid; it is produced by normal prostate cells. The molecule consists of approximately 92% protein and 8% carbohydrate. This enzyme participates in the dissolution of the seminal fluid coagulum and plays an important role in fertility. The highest amounts of PSA are found in the seminal fluid; some PSA escapes the prostate and can be found in the serum. This serum component has been used to track the response to therapy in men with prostate cancer.
