Triiodothyronine (T3)-HRP Antigen

A horseradish peroxidase-conjugated antigen preparation from Antibodies.com delivers a ready-to-use tracer for competitive immunoassay development targeting triiodothyronine, the thyroid hormone central to metabolic regulation. The liquid conjugate pairs the T3 molecule directly with HRP enzyme, eliminating secondary antibody incubation and supporting direct enzymatic signal generation. Supplied in a 1 ml vial, the reagent supports small-batch assay optimization, antibody screening workflows, and clinical research centered on thyroid function evaluation. Laboratories deploy this conjugate in ELISA plate setups to establish standard curves, calibrate detection antibodies, or run inhibition-based assays. The horseradish peroxidase label produces a chromogenic readout when paired with substrates such as TMB, enabling absorbance-based quantitation on standard plate readers. Because the conjugate carries the enzyme already, protocols run faster with fewer incubation steps compared with indirect detection schemes. The reagent is intended for research use only and supports laboratories developing thyroid hormone immunoassays or characterizing antibody specificity. Proper handling includes refrigerated storage to preserve enzymatic activity and protection from light to maintain conjugate stability. Each vial delivers 1 ml of the liquid antigen-HRP conjugate, ready for dilution into working assay buffer.
