Nqi-efficiency lepu COVID-19 antigen ceev kuaj cov khoom siv AMRPA77 Cov ntsiab lus
Coronavirus, raws li tsev neeg tus kab mob loj, yog ib tus kab mob RNA zoo uas muaj lub hnab ntawv.Tus kab mob no paub tias ua rau muaj mob loj xws li mob khaub thuas, Middle East Respiratory Syndrome (MERS), thiab mob hnyav ua pa nyuaj (SARS).

Cov protein tseem ceeb ntawm SARS-CoV-2 yog N protein (Nucleocapsid), uas yog cov khoom noj muaj protein nyob hauv tus kab mob.Nws tau txais txiaj ntsig zoo ntawm β-coronaviruses thiab feem ntau yog siv los ua cov cuab yeej rau kev kuaj mob tus mob coronaviruses.ACE2, ua ib qho tseem ceeb receptor rau SARS-CoV-2 nkag mus rau cov hlwb, yog qhov tseem ceeb heev rau kev tshawb fawb txog kev kis kab mob.

Nqi-efficiency lepu COVID-19 antigen quick test kit AMRPA77 Principple
Daim npav kuaj tam sim no yog ua raws li cov tshuaj tiv thaiv kab mob-antigen tshwj xeeb thiab kev siv tshuab immunoanalysis.Daim npav xeem muaj cov colloidal kub sau npe SARS-CoV-2 N protein monoclonal antibody uas yog pre-coated rau ntawm lub ncoo ua ke, matched SARS-CoV-2 N protein monoclonal antibody immobilized nyob rau hauv Test area (T) thiab coj antibody nyob rau hauv qhov zoo. tswj cheeb tsam (C).

Thaum lub sij hawm kuaj, N protein nyob rau hauv cov qauv ua ke nrog cov colloidal kub sau SARS-CoV-2 N protein monoclonal antibody uas yog pre-coated rau ntawm lub ncoo ua ke.Cov conjugates migrate upwards nyob rau hauv capillary nyhuv, thiab tom qab ntawd ntes tau los ntawm N protein monoclonal antibody immobilized nyob rau hauv lub xeem cheeb tsam (T).

Qhov siab dua cov ntsiab lus ntawm N protein nyob rau hauv cov qauv, qhov ntau conjugates captures thiab cov xim tsaus nyob rau hauv qhov chaw kuaj yog.

Yog tias tsis muaj tus kab mob hauv cov qauv lossis cov ntsiab lus ntawm tus kab mob qis dua qhov kev kuaj pom, ces tsis muaj xim pom nyob rau hauv qhov chaw kuaj (T).

Txawm hais tias muaj los yog tsis muaj tus kab mob nyob rau hauv cov qauv, ib tug liab kab txaij yuav tshwm nyob rau hauv lub zoo tswj cheeb tsam (C).

Cov kab txaij ntshav nyob rau hauv qhov chaw tswj kom zoo (C) yog ib qho kev ntsuas rau kev txiav txim siab seb puas muaj cov qauv txaus thiab seb cov txheej txheem chromatography puas zoo li qub.
