The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.\nTo minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay procedure summary\u003c\/b\u003e: 1. Prepare all reagents, samples and standards;\n2. Add 50µL standard or sample to each well.\n    And then add 50µL prepared Detection Reagent A immediately.\n    Shake and mix. Incubate 1 hour at 37°C;\n3. Aspirate and wash 3 times;\n4. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;\n5. Aspirate and wash 5 times;\n6. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C;\n7. Add 50µL Stop Solution. Read at 450 nm immediately.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTest principle\u003c\/b\u003e: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to T4 has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled T4 analogues and unlabeled antigen (Standards or samples) with the pre-coated antibody. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of fT4 in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of fT4 in the sample.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch Area\u003c\/b\u003e: -\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReferences Citing This Product\u003c\/b\u003e: \u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28119573\"\u003eElevated Thyroid Peroxidase Antibody Increases Risk of Post-partum Depression by Decreasing Prefrontal Cortex BDNF and 5-HT Levels in Mice\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/pdfs.semanticscholar.org\/cfe6\/40b46e96087a777950f4287f3f4b0318c31e.pdf\"\u003eEffect of Selenium and Zinc Supplementation on Hypothyroidism in Rats\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/28713236\"\u003eModulation of Calcitonin, Parathyroid Hormone, and Thyroid Hormone Secretion by Electrical Stimulation of Sympathetic and Parasympathetic Nerves in Anesthetized Rats.\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0006899319303609\"\u003eAge-Dependent Evaluation of Long-Term Depression Responses in Hyperthyroid Rats: Possible Roles of Oxidative Intracellular Redox Status\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/link.springer.com\/article\/10.1007\/s12576-019-00691-8\"\u003eThyroxin and calcitonin secretion into thyroid venous blood is regulated by pharyngeal mechanical stimulation in anesthetized rats\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"http:\/\/www.ijcem.com\/files\/ijcem0089740.pdf\"\u003eApatinib inhibits proliferation of different lung cancer cells in vitro and in vivo by promoting apoptosis and inducing cell cycle arrest\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e\u003ca href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/33576121\"\u003eEffect of L©\\thyroxine administration on long©\\term potentiation and accompanying mitogen©\\activated protein kinases in rats\u003c\/a\u003e\u003cp\u003e \u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48696706531428,"sku":"CEA185Ge","price":871.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_a3fb9097-affe-448d-a12b-8ec5a5b40d65.jpg?v=1783134830","url":"https:\/\/www.genebiosystems.com\/en-fr\/products\/ft4-elisa-kit-for-general-species","provider":"GeneBio ","version":"1.0","type":"link"}
