Spike glycoprotein ayaa ka jira dusha sare ee coronavirus-ka cusub 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 tijaabada Antigen-ka ee is-tijaabinta ah ee loogu magac daray "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" kaas oo loogu talagalay in lagu ogaado tayada SARS-CoV-2 Antigen ee sanka swab shaybaarka iyada oo loo marayo ogaanshaha borotiinka Ntro.

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.
