Spike glycoprotein ayaa ka jira korka novel coronavirus oo si fudud isu beddelay sida Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) iyo Omicron (B. 1.1.529, BA.2, BA.4, BA.5).

Nucleocapsid fayrasku wuxuu ka kooban yahay borotiinka nucleocapsid (N borotiinka gaaban) iyo RNA.borotiinka N waa mid xasiloon, waana saamiga ugu badan ee borotiinnada qaab dhismeedka fayraska iyo dareenka sare ee ogaanshaha.

Iyada oo ku saleysan astaamaha borotiinka N, Monoclonal antibody ee borotiinka N ee ka soo horjeeda coronavirus-ka cusub ayaa lagu doortay horumarinta iyo naqshadeynta xirmada tijaabinta Antigen-ka ee is-tijaabinta ee loogu magac daray "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" kaas oo loogu talagalay ogaanshaha tayada leh ee SARS-CoV-2 Antigen ee muunadaha suufka sanka ee vitro iyada oo loo marayo ogaanshaha borotiinka N.

Taasi waa in la yiraahdo, cadaadiska mutant glycoprotein ee hadda jira sida Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) iyo Omicron (B.1.1) .529, BA.2, BA.4, BA.5).Waxqabadka SARS-CoV-2 Antigen Rapid Test (Colloidal Gold) ee ay soo saartay shirkadeena ma saameyn doonto.
