Anti-Free PSA Antibody [108]

Free Prostate Specific Antigen (free PSA), the unbound fraction of PSA that circulates in blood without bound protease inhibitors, is selectively recognized by the Clone 108 mouse monoclonal IgG2a antibody from Antibodies.com. The reagent is supplied as a 100 µg lyophilised preparation in a vial format suitable for reconstitution into working aliquots, and it is validated for ELISA workflows with human samples.

The unconjugated format allows direct biotinylation, coupling to reporters, or pairing with labelled secondary reagents for custom immunoassay development. The IgG2a isotype is broadly compatible with standard anti-mouse secondary antibodies and facilitates matched-pair design alongside other anti-PSA clones. Research applications include prostate cancer biomarker studies, free-to-total PSA ratio investigations, and assay optimization in clinical research settings. Reconstitution into buffer preserves activity for downstream immunodetection protocols.
