Given normal levels of thyroid hormone-binding proteins, hyperthyroidism is characterized by increased levels of circulating T4, hypothyroidism by decreased levels. Exceptions to this parallelism between thyroid status and total T4 concentration are found. Levels of TBG are known to be altered under various physiological, pharmacological and genetic conditions. Elevated T4 levels may be obtained when TBG levels are high, as in pregnancy, acute intermittent porphyria, hyperproteinemia, hereditary TBG elevati.\u003c\/p\u003e\n\u003ch2\u003eAssay Principle\u003c\/h2\u003e\n\u003cp\u003eThis assay employs a two-site sandwich ELISA to quantitate T4 in samples. An antibody specific for T4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyT4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for T4 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of T4 bound in the initial step. The color development is stopped and the intensity of the color is measured.\u003c\/p\u003e\n\u003ch2\u003ePerformance Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSensitivity\u003c\/th\u003e\n\u003ctd\u003e1.42 ng\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetection Range\u003c\/th\u003e\n\u003ctd\u003e3.70-300 ng\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Assay Time\u003c\/th\u003e\n\u003ctd\u003e3.5–5 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Sample Types\u003c\/th\u003e\n\u003ctd\u003eserum, plasma, cell culture supernatant, tissue homogenate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd\u003eSheep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetection Method\u003c\/th\u003e\n\u003ctd\u003eColorimetric (TMB\/HRP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003e4°C (short-term); -20°C (long-term)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cspan class=\"bhp-qc-badge\"\u003e✓ Research-Grade Validation\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eSafety \u0026amp; Regulatory\u003c\/h2\u003e\n\u003cdiv class=\"bhp-warning-box\"\u003e\n\u003cstrong\u003eResearch Use Only (RUO).\u003c\/strong\u003e This product is intended for research purposes only and is not approved for diagnostic, therapeutic, or clinical use.\u003c\/div\u003e\n\u003cp\u003eHandle reagents in accordance with institutional biosafety guidelines.
