Product Details

Prostate Specific Antigen (PSA) is a 33 Kda protein found in 3 forms: free, bound to alpha-1-antichymotrypsin, and bound to alpha-2-macroglobulin. Measuring the ratio of free to total PSA can be used as a screening and diagnostic marker for prostate cancer.

Our Human Free PSA (f-PSA) ELISA Kit specifically detects the free, unbound form of PSA in serum or plasma samples as well as in lysates. The kit does not detect the two bound forms.
