SARS-CoV-2 Antigen Rapid Test Kit yog lateral flow chromatographic immunoassay.
Test cassette muaj xws li:
1) burgundy coloured conjugate ncoo uas muaj recombinant antigen conjugated nrog colloid kub (monoclonal nas anti SARS-CoV-2 antibody conjugates) thiab luav IgG-kub conjugates
2) nitrocellulose membrane sawb uas muaj cov qhab nia xeem (T bands) thiab pawg tswj hwm (C band).
T band yog pre-coated nrog monoclonal mouse anti- SARS-CoV-2 NP antibody rau kev kuaj pom ntawm SARS-CoV-2 NP antigen, thiab C band yog pre-coated nrog tshis anti luav IgG.Thaum lub ntim ntim txaus ntawm cov qauv kuaj tau muab xa mus rau hauv cov qauv zoo ntawm cov ntawv xeem, cov qauv txav los ntawm kev ua haujlwm capillary thoob plaws lub cassette.SARS-CoV-2 virus yog muaj nyob rau hauv cov qauv yuav khi rau monoclonal mouse anti- SARS-CoV-2 NP antibody conjugates.Lub immunocomplex yog tom qab ntawd ntes ntawm daim nyias nyias los ntawm pre-coated nas anti- SARS-CoV-2 NP antibody, tsim burgundy xim T band, qhia txog Covid-19 NP antigen qhov kev kuaj pom zoo.Tsis muaj kev xeem qhab (T) qhia tias qhov tshwm sim tsis zoo.Qhov kev ntsuam xyuas muaj kev tswj hwm sab hauv (C band) uas yuav tsum tau nthuav tawm cov xim burgundy ntawm cov tshuaj tiv thaiv kab mob ntawm tshis anti luav IgG / luav IgG-kub conjugate tsis hais txog xim kev loj hlob ntawm ib qho ntawm cov qhab nia xeem.Txwv tsis pub, cov txiaj ntsig kev xeem tsis raug cai, thiab cov qauv yuav tsum tau rov kuaj dua nrog lwm lub cuab yeej.
