PSA ELISA Kit Background Information:
Human prostate-specific antigen (PSA) is a serine protease, a single chain Glycoprotein. PSA is immunologically specific for prostatic tissue, it is present in normal, benign hyperplastic, and malllignant prostatic tissue, in metastatic prostatic carcinoma, and also in prostatic fluid and seminal plasma. PSA is not present in any other normal tissue obtained from men, nor is it produced by cancers of the breast, lung, colon, rectum, stomach, pancreas or thyroid. PSA is functionally and immunologically different from prostatic acid phosphatase (PAP). Serum PSA is one of the most useful tumor markers in oncology. It may serves as an accurate marker for assessing response to treatment in patients with prostatic cancer. Therefore, measurement of serum PSA concentrations can be an important tool in monitoring patients with prostatic cancer and in determining the potential and actual effectiveness of surgery or other therapies. Recent studies also indicate that PSA measurements can enhance early prostate cancer detection when combined with digital rectal examination.

PSA ELISA Test Principle:
The PSA ELISA test is a solid phase two-site immunoassay. Rabbit anti-PSA is coated on the surface of the microtiter wells and another anti-PSA monoclonal antibody labeled with HRP is used as the tracer. The PSA molecules present in the standard solution or serum are sandwiched between the two antibodies. After incubation and washing, the enzymatic reaction develops a color which is proportional to the amount of PSA molecules present in the assay. For additional details please refer to the instructions for use.
