Human Free Prostate Specific Antigen ELISA Kit

This quantitative immunoassay from Antibodies.com measures free prostate specific antigen in human research specimens, supporting studies of prostate cancer biomarkers and the differential evaluation of benign prostatic conditions versus malignant disease. The kit is supplied as a microplate-format research use only product, with individual vials of pre-coated plate, detection antibody concentrate, calibrated standards, and buffer reagents sufficient to generate a standard curve for free PSA quantification. Investigators calculating the free-to-total PSA percentage can pair this assay with a matched total PSA kit to derive clinical ratio values from patient serum samples. All reagents are intended for in vitro research workflows in clinical and translational laboratories, with each component lot validated for performance in free antigen capture applications.
