Product Overview
| Description | Prostate Specific Antigen (PSA, Kallikrein-3, Kallikrein III, Seminin, Semenogelase, γ-Seminoprotein, P-30 antigen) is a chymotrypsin-like serine protease (kallikrein family) produced by the prostate epithelium and abundant in seminal fluid. PSA can be detected in the sera of patients with prostatic carcinoma. It is predominantly complexed to a liver-derived serine protease inhibitor, alpha-1-antichymotrypsin (ACT). A higher proportion of serum PSA is complexed to ACT in prostate cancer than in benign prostate hyperplasia. Anti-PSA is useful in the positive identification of metastatic deposits of prostatic origin. Applications: Suitable for use in ELISA, as an immunogen for antisera production, and as a tracer for iodination. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. |
