The human PSA ELISA Kit is intended to measure human PSA in serum, plasma, or tissue homogenates. This assay uses the bi-antibody sandwich technique and enzyme-substrate chromogenic reaction to quantify human PSA concentration. The intensity of the colored product is positively proportional to the concentration of PSA present in the sample. This human PSA ELISA kit has high specificity and excellent sensitivity.
PSA is a serine protease with chymotrypsin-like enzymatic activity. It is expressed predominantly in the prostate and a subset of proximal renal tubules. It mainly functions to degrade the gel-forming proteins semenogelins I and II in semen after ejaculation. This process causes the seminal clot to liquefy and motile sperm to be released, allowing the spermatozoa to pass through the female reproductive canal. PSA level in semen has been shown to correlate with sperm motility, suggesting that PSA level/activity can affect fertility. PSA is a credentialed imaging and therapy (theranostic) target for the detection and treatment of prostate cancer.
