Anti-Free PSA Antibody [103]

Supplied as a lyophilised pellet in a 100 µg vial, this unconjugated mouse monoclonal IgG2a (clone 103) is raised against the unbound, non-complexed form of Prostate Specific Antigen and is intended for ELISA workflows. The antibody selectively recognizes free PSA rather than the alpha-1-antichymotrypsin-bound fraction, supporting research into prostate cancer screening and the free-to-total PSA ratio used to differentiate benign prostatic hyperplasia from malignancy. Provided by Antibodies.com as a primary antibody for research use only, the reagent is reactive with human samples, carries no fluorescent or enzymatic label, and is suited to immunoassay platforms where investigators conjugate the antibody in-house. The lyophilised format should be stored refrigerated with desiccant, protected from light, and reconstituted in PBS or deionized water according to the supplied data sheet prior to use in downstream applications.
