T4 yog cov khoom tseem ceeb ntawm cov thyroid secretion, thiab nws kuj yog ib qho indis pensable tivthaiv ntawm kev ncaj ncees ntawm hypothalamic-anterior pituitary-thyroid regulatory system.Nws tsub kom lub basal metabolic tus nqi thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv kev loj hlob ntawm tag nrho cov hlwb ntawm lub cev.T4 yog khaws cia hauv cov thyroid follicles ua ke nrog thyroglobulin, thiab tso tawm thiab tso tawm raws li kev tswj hwm ntawm TSH.Ntau tshaj 99% ntawm T4 hauv cov ntshav muaj nyob rau hauv daim ntawv ntawm kev khi rau lwm cov proteins.Kev kuaj tag nrho T4 hauv cov qauv ntshav tuaj yeem qhia tau tias koj cov thyroid ua haujlwm txawv txav.
Cov khoom no siv fluorescence immunochromatography kom paub ntau npaum li cas cov ntsiab lus ntawm cTT4 hauv dev ntshav / ntshav.Lub hauv paus ntsiab lus: T thiab C kab yog cim rau ntawm nitrocellulose daim nyias nyias, T kab yog coated nrog cTT4 antigen a, thiab cov ntaub ntawv khi yog txau nrog ib tug fluorescent nanomaterial lo lo ntxhuav antibody b uas muaj peev xwm paub txog cTT4.Lub cTT4 hauv cov qauv yog thawj zaug sau nrog nanomaterial.Cov tshuaj tiv thaiv b khi los ua ib qho nyuaj, thiab tom qab ntawd chromatographs upwards.Lub complex sib tw nrog T-line antigen a thiab tsis tuaj yeem ntes tau;Ntawm qhov tsis sib xws, thaum tsis muaj cTT4 hauv cov qauv, cov tshuaj tiv thaiv b khi rau antigen a.Thaum lub teeb excitation yog irradiated, cov khoom nano emits lub teeb liab fluorescent, thiab lub zog ntawm lub teeb liab yog inversely proportional rau qhov concentration ntawm cTT4 nyob rau hauv cov qauv.
Txij li thaum nws tsim, peb lub Hoobkas tau tsim thawj cov khoom hauv ntiaj teb nrog kev ua raws li txoj cai
ntawm qhov zoo ua ntej.Peb cov khoom tau txais lub koob npe nrov hauv kev lag luam thiab muaj txiaj ntsig zoo ntawm cov neeg siv khoom tshiab thiab qub ..
