Chemiluminescence Immunoassay Technique yog dab tsi?
Cov txheej txheem Chemiluminescence immunoassay (CLIA) yog ib txoj kev kuaj mob hnyav heev uas siv los kuaj xyuas thiab ntsuas ntau yam khoom hauv cov qauv tshuaj lom neeg. Nws yog dav siv nyob rau hauv cov cheeb tsam xws li kev soj ntsuam kuaj mob, tshuaj nrhiav pom, ib puag ncig tsom xam, thiab kev ntsuam xyuas zaub mov kev nyab xeeb. Cov txheej txheem txiav-ntug no tau hloov pauv lub teb ntawm immunoassays los ntawm kev muab kev txhim kho rhiab heev thiab dav dynamic ntau piv rau lwm txoj kev.
Lub hauv paus ntsiab lus ntawm Chemiluminescence Immunoassay Technique
Lub hauv paus ntsiab lus tom qab chemiluminescence immunoassay txheej txheem yog lub cim ntawm lub teeb raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv ntawm cov tshuaj ntsuam xyuas ntawm kev txaus siab thiab ib qho kev sib khi molecule. Hauv CLIA ib txwm, cov tshuaj ntsuam xyuas tau lees paub los ntawm cov tshuaj tiv thaiv kab mob lossis cov tshuaj tiv thaiv kab mob, uas ua haujlwm raws li kev khi molecule. Thaum cov tshuaj ntsuam xyuas thiab cov binding molecule sib cuam tshuam, lawv tsim ib qho kev tiv thaiv kab mob.
Qhov kev tiv thaiv kab mob no yog tom qab ntawd sib xyaw nrog chemiluminescent substrate, uas muaj peev xwm tsim lub teeb thaum ua kom tiav. Lub substrate feem ntau muaj cov molecule hu ua luminophore, uas dhau los ua lub zog hloov mus rau lub xeev zoo siab thiab tawm lub teeb thaum nws rov qab los rau hauv av. Cov tshuaj tiv thaiv chemiluminescent yog catalyzed los ntawm ib qho enzyme, xws li horseradish peroxidase los yog alkaline phosphatase, uas yog conjugated rau lub binding molecule.
Qhov kev siv ntawm lub teeb emission yog ncaj qha proportional rau tus nqi ntawm cov analytes tam sim no nyob rau hauv cov qauv. Lub teeb emitted no yog ntsuas los ntawm kev ntsuas tshwj xeeb hu ua luminometer. Lub teeb liab tau txais los ntawm lub luminometer raug kaw thiab tshuaj xyuas los txiav txim siab qhov concentration lossis muaj cov tshuaj ntsuam xyuas hauv cov qauv.
