Anti-Thyroxine (T4) Antibody

From the Antibodies.com primary antibodies catalogue comes this mouse monoclonal reagent raised against the thyroid hormone Thyroxine, also known as T4, suitable for ELISA-based immunoassay workflows. The reagent is supplied at a 1 mg pack size as an ion exchange-purified monoclonal antibody in unconjugated form, ready for direct coupling or for use as a capture/detection reagent in antibody pair development. Clonality is monoclonal, with the antibody expressed as an IgG2a subclass, raised in mouse host cells and directed against T4 (Thyroxine) using a T4-BSA immunogen, as reflected in the broader family of T4 clones listed in the Antibodies.com catalogue. Because the antibody is unconjugated and formulated as a purified immunoglobulin preparation rather than a labelled detection reagent, it can be paired in-house with HRP, biotin, ruthenium, alkaline phosphatase or fluorophore tags according to the assay platform; the Antibodies.com anti-T4 family is also represented in formats marketed for FIA (fluorescent and luminescent immunoassay) development. Specificity is for T4 (thyroxine), the major circulating thyroid hormone produced by the thyroid gland, making this clone useful for the quantification of total or free T4 in research samples. The reagent is supplied as a research-use-only primary antibody — not for diagnostic or therapeutic use — and should be stored according to the small-volume protein guidance typical for purified IgG preparations (typically refrigerated short term at 2–8 °C, with aliquoting and freezing recommended for long-term storage to preserve activity). Among the catalogue siblings, the IgG2a-bearing clone sits alongside IgG2b, kappa and IgG1, kappa variants, giving developers flexibility to match isotype to secondary reagents or to avoid isotype cross-reactivity in paired assays. Each lot is generated under Antibodies.com quality systems, with the 1 mg bulk format intended for teams building immunoassays, calibrator panels, or antibody-pair screening studies where a reliable anti-T4 capture is required.
