Sample Pad thiab Conjugate Pad Dab tsi yog qhov ntsuas sab hauv immunochromatography. Lateral immunoassay (cov tshuaj tiv thaiv kab mob ib sab) yog lub hauv paus tseem ceeb ntawm kev ntsuas kev saib xyuas (POCT), nws cov ntsiab lus tseem yog kev tiv thaiv kab mob tiv thaiv kab mob antigen. Txawm li cas los xij, cov txheej txheem ib txwm yog teeb tsa cov tshuaj tiv thaiv kab mob antigen rau ntawm 96-phaj zoo, lossis saum npoo ntawm cov hlau nplaum microspheres, thaum lub ntsej muag tiv thaiv kab mob immunochromatography tom qab tso cov tshuaj tiv thaiv kab mob hauv cov ntxeem tau nitrocellulose membrane (NC membrane) Yog li, nws kuj tseem hu ua kuaj kab xev kuaj pom.
Kuaj kab qauv rau sab hauv immunochromatography Lub hauv paus tseem ceeb ntawm kev ntsuas tshuaj tiv thaiv kab mob tom ntej suav nrog nqus cov ntawv, daim nyias nyias chromatographic, cov ntawv sib txuas thiab cov ncoo piv txwv, thiab lub hauv paus yas phaj txhawb nqa txhua yam khoom siv. Cov kua ua kua tau ntxiv los ntawm cov ntaub qhwv ntaub thiab ntws mus rau sab ntawm daim ntawv nqus dej. Thaum dhau los ntawm cov ntaub qhwv sib txuas, cov tshuaj tiv thaiv kab mob (colloidal kub, fluorescent microspheres, thiab lwm yam) ntawm cov ntaub qhwv sib txuas tau tso tawm, thiab ua haujlwm nrog cov tshuaj ntsuam hauv cov qauv thaum lub sijhawm txheej txheem ntws, thiab tom qab ntawd tsau rau kab kab pom ntawm
NC membrane ua (Kab Xeem) Cov tshuaj tiv thaiv kab mob ntes thiab sau ua ke los ua lub teeb pom kev zoo.
Kev ntsuam xyuas sab nraub qaum originated nyob rau hauv 1990s. Nrog kev ruaj ntseg ntawm colloidal kub npaj thev naus laus zis, txoj kev kuaj mob sai tau tsim ua ke nrog immunoassay tau tsim. Raws li kev txhim kho ntawm kev soj ntsuam, kev siv thev naus laus zis thev naus laus zis tau dhau los ntawm peb theem tseem ceeb: kub colloidal, dyed latex microspheres, thiab fluorescent microspheres. Raws li qhov tshwm sim, qhov kev tshawb pom tseem tau dhau los ntawm peb theem: kev tsim nyog, ib nrab qhov ntau, thiab ntau npaum li cas.
Qauv Pad Cov ntaub qhwv ntaub tuaj yeem siv los ua ntau txoj haujlwm, qhov tseem ceeb tshaj plaws uas yog txhawm rau txhawb nqa ib yam thiab tswj kev faib khoom ntawm cov qauv ntawm cov ntaub qhwv sib txuas. Nws kuj tseem tswj hwm tus nqi uas cov kua nkag mus rau hauv lub ncoo sib txuas, yog li tiv thaiv lub cuab yeej los ntawm kev hla. Thaum impregnated nrog cov protein, xab npum, tackifiers thiab tsis qab ntsev. Feem ntau muaj ob hom ntaub ntawv siv los ua qauv pawm: cov lim cellulose fiber thiab cov ntxaij lim dej. Los ntawm kev ntxiv cov tshuaj retarder rau cov qauv ntsuas phoo, qhov retardation ntawm daim nyias nyias tuaj yeem tshem tawm. Txoj hauv kev no yuav yooj yim dua thiab raug nqi ntau dua li sim ncaj qha thaiv cov membrane. Tshwj tsis yog tias cov tshuaj tiv thaiv kab mob (lossis antigen) txuas nrog covalently txuas rau lub ntsuas qhov ntsuas, thaum muaj cov thaiv cov protein lossis cov xab npum, nws raug nquahu kom tsis txhob qhuav cov tshuaj reagents mus rau hauv cov ntaub qhwv.
Cov ntaub qhwv ntaub tuaj yeem siv tau rau: Ua kom cov qauv viscosity ntau dua (kho cov yam ntxwv ntws). Txhim kho lub peev xwm ntawm kev kuaj kom yaj cov tshuaj reagents. Tiv thaiv kev sib txuas thiab tshuaj ntsuam los ntawm qhov tsis tshwj xeeb rau cov khoom siv nqes hav. Hloov kho cov khoom siv tshuaj lom neeg ntawm cov qauv ua kom nws sib xws nrog cov tshuaj tiv thaiv kab mob ntawm kab xeem. Txhawb nqa cov dej ntws sib xws ntawm cov qauv ua raws daim nyias nyias. Kev ntxiv cov protein thiab xab npum thiab surfactants tuaj yeem txhawb kev rov sib txuas ntawm cov conjugates, txo qhov kev sib khi ntawm cov tsis tshwj xeeb khi, thiab tuaj yeem txo qis cov tshuaj analyte adsorption membrane.
Conjugate ncoo Conjugate pawm tuaj yeem ua haujlwm ntau yam, qhov tseem ceeb tshaj plaws uas yog kev hloov pauv ntawm cov tshuaj reagents thiab kuaj cov qauv mus rau daim nyias nyias. Thaum cov qauv ntws mus rau hauv cov ntaub qhwv sib txuas, cov tshuaj reagent tau yaj, nqa cov ntaub qhwv, thiab txav mus rau hauv daim nyias nyias ua ke nrog cov qauv. Lub luag haujlwm tseem ceeb ntawm cov ntaub qhwv sib txuas yog xa cov khoom sib piv raws li qhov ntim tas mus li ntawm cov qauv ntawm txhua qhov kev xeem mus rau daim nyias nyias.
Cov khoom siv sib txuas zoo tshaj plaws muaj cov khoom hauv qab no: Tsawg yam tsis tshwj xeeb. Yog tias kuaj pom cov tshuaj reagent lossis tshuaj ntsuam txuas rau lub ncoo khi, nws yuav tsis tuaj yeem tsim cov kab mob tiv thaiv kab mob ntawm txoj kab ntsuas, yog li txo lub teeb liab lub zog thiab kev nkag siab. Cov yam ntxwv zoo ib yam Cov yam ntxwv tsis sib xws tuaj yeem tsim teeb meem kev ua haujlwm loj. Yog tias cov khoom siv tsis tau tso tus qauv sib npaug ntawm daim nyias nyias, cov tshuaj reagent tuaj yeem xa mus rau daim nyias nyias thiab cov kab tuaj yeem tshwm sim raws li cov qauv txav mus los ntawm daim nyias nyias. Yog li ntawd, cov cim tsis sib xws yuav tshwm ntawm qhov ntsuas thiab tswj kab. Lub txaj ntim tau zoo ib yam. Thaum thauj nws mus rau hauv lub ncoo sib txuas los ntawm kev raus dej, tus nqi ntawm cov tshuaj reagent hauv txhua qhov ntsuas ntsuas nyob ntawm lub txaj ntim ntawm cov khoom. Yog tias qhov ntim ntawm lub txaj sib txawv heev, lub teeb liab sib txawv yuav raug pom txawm tias tag nrho lwm cov khoom siv ntawm cov hlua tseem tsis hloov pauv. Tsawg rho tawm. Ntxiv nrog rau cov tshuaj rho tawm, cov khoom siv kuj yuav tsum tsis pub muaj cov khoom uas tuaj yeem thaiv cov membrane ntawm qhov sib txuas sib txuas / daim nyias nyias. Cov yam ntxwv ua lub vev xaib zoo thiab ua kom zoo ib yam. Cov cwj pwm no tseem ceeb heev rau kev koom ua ke ntsuas cov kab ntau lawm thiab hloov pauv cov kua mus rau daim nyias nyias.
Qhov sib txawv ntawm cov qauv ncoo thiab cov ntaub qhwv sib txuas Ob leeg tau siv los khaws cov qauv sib txawv. Cov ntaub qhwv sib txuas yog cov nqa khoom rau cov ntawv lo rau cov protein, thaum lub ncoo piv txwv yog tus nqa khoom rau kev kho ua ntej ntawm cov tshuaj lom biochemical. Yog li ntawd, txiav txim siab txog kev nyob ua ke ntev nrog cov protein, cov ntaub ntawv sib txuas tuaj yeem tsuas yog tswj hwm pH nruab nrab, tsis muaj ntsev ntsev tsawg, thiab lwm yam, los tsim qhov chaw khaws cia zoo rau cov protein. Cov ntaub qhwv lub ntsej muag tau ntsib nrog cov qauv piv txwv nyuaj dua, yog li nws xav tau ntau dua kev kho ua ntej thiab muaj peev xwm pom.
Nta thiab daim ntawv thov ntawm cov khoom siv immunochromatography ib sab Los ntawm kev pom ntawm kev siv tshuab thev naus laus zis, kev ntsuas ib sab ntws tau dhau los ntawm ob peb theem xws li kub colloidal, tsuas yog siv cov xim yas microspheres, thiab fluorescent microspheres. Ib qho ntxiv, quantum dot fluorescence thiab cov khoom sib nqus tau tsim nyob rau xyoo tas los no. Colloidal kub thiab latex microspheres feem ntau yog txiav txim los ntawm lub qhov muag liab qab rau kev hloov xim, feem ntau tsuas yog rau kev txheeb xyuas qhov muaj txiaj ntsig, thiab xav tau kev koom tes nrog cov cuab yeej kom ua tiav ib nrab qhov ntau. Nrog kev pab los ntawm kev teeb tsa lub teeb fluorescence thiab lub tshuab ntsuas hluav taws xob kom nyeem cov teeb ci siv hluav taws xob, cov tshuab fluorescent microspheres tuaj yeem ua tiav qhov ntsuas pom, uas yog lub hauv paus ntawm kev txhim kho niaj hnub no.
Ntsiab lus: Qhov nruab nrab ntws immunochromatographic yog txoj kev tiv thaiv kab mob sai sai uas suav nrog kev tiv thaiv kab mob thiab chromatography. Nws tsuas yog siv rau kev kuaj pom tus kab mob, cov tshuaj hormones, tshuaj, thiab cov tshuaj metabolites. Lub hauv paus yog txhawm rau txheeb xyuas cov tshuaj antigens lossis cov tshuaj tiv thaiv kab mob los ntawm daim ntawv lo tshuaj xyuas yam khoom.
BALLYA tau cog lus rau kev tshawb fawb ntawm kev tshawb fawb txog keeb kwm thiab muaj nws tus kheej qhov kev paub dhau los thiab kev paub dhau los ntawm kev siv cov tshuaj tiv thaiv kab mob sab hauv. Siv cov tshuaj tiv thaiv kab mob sab hauv, Ballya tau ua tiav tsim ntau yam
cov khoom siv ceev nrawm xeem rau cov khoom siv mis nyuj, zib ntab, cov khoom hauv dej, tshuaj tua kab, ua kom tsis muaj menyuam, kab mob tsiaj thiab kab mob tsiaj txhu. Yav tom ntej, Ballya tseem yuav ua qhov kev tshawb fawb tob ntxiv ntawm ntau yam ntawm kev sim.
