【Cov ntsiab cai ntawm tus txheej txheem】

2019-nCOV IgM Antibody Assay Reagent Kit (CMIA) yog ob-kauj ruam immunoassay siv cov khoom sib nqus particle chemiluminescence technology. Nws tuaj yeem txiav txim siab qhov muaj cov tshuaj tiv thaiv-2019-nCOVigM cov tshuaj tiv thaiv hauv tib neeg cov ntshav lossis ntshav ntshav.

Thaum lub sij hawm cov tshuaj tiv thaiv, thawj kauj ruam yog protein khi los ntawm kev sib xyaw cov qauv nrog muaj zog paramagnetic hais coated nrog 2019-nCoV nuclear protein antigen. Tom qab ntxuav, cov alkaline phosphataselabeled murine anti-tib neeg IgM monoclonal antibody yog ntxiv nyob rau hauv lub kauj ruam thib ob los tsim ib tug sib nqus particle-nucleoprotein_anti-2019-nCoV-IgM murine-anti-IgM-ALP-enzyme tshuaj sib tov. Tom qab lwm lub voj voog ntxuav, lub substrate ntawm alkaline phosphatase ntxiv rau cov tshuaj tiv thaiv sib tov. Qhov tshwm sim chemiluminescence cov tshuaj tiv thaiv yog ntsuas nyob rau hauv cov txheeb ze lub teeb units (RLU). The concentration of the anti-2019-nCoV -IgM antibody in the sample is proportional to the amount of relative light units (RLU) of the mix. Yog li cov txiaj ntsig tuaj yeem siv los txheeb xyuas qhov muaj nyob ntawm IgM hauv cov qauv thiab pab txiav txim seb tus neeg mob puas tau kis tus kab mob 2019-nCoV.
