Free PSA

Free PSA

The Fortress Diagnostics Free Prostate Specific Antigen (PSA) CLIA kit is intended for the quantitative determination of free PSA concentration in human serum by a microplate chemiluminescence assay. 

Prostate Specific antigen (PSA) is a serine protease with chymotrypsin-like activity. The protein is a single chain glycoprotein with a molecular weight of 28.4 kDA. PSA derives its name from the observation that it is a normal antigen of the prostate but is not found in any other normal or malignant tissue.
