Li-glycoprotein tse matla li teng holim'a coronavirus e ncha 'me li fetoha habonolo joalo ka Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) le Omicron (B.1.1.529, BA.2, BA.4, BA.5).

Nucleocapsid ea vaerase e entsoe ka protheine ea nucleocapsid (protheine ea N ka bokhutšoanyane) le RNA. Protheine ea N e tsitsitse ka mokhoa o batlang o lekana, karolo e kholo ka ho fetisisa liprotheineng tsa sebopeho sa vaerase le kutloisiso e phahameng ha e fumanoa.

Ho latela litšobotsi tsa protheine ea N, antibody ea monoclonal ea protheine ea N khahlanong le coronavirus e ncha e khethiloe ntlafatsong le moralo oa kit ea rona ea Tlhahlobo ea Antigen e itlhahlobang e bitsoang "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" e reretsoeng ho lemoha boleng ba SARS-CoV-2 Antigen disampoleng tsa swab ea nko ka har'a vitro ka ho lemoha protheine ea N.

Ke hore, bakeng sa mofuta oa hona joale oa spike glycoprotein mutant joalo ka Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) le Omicron (B.1.1.529, BA.2, BA.4, BA.5). Ts'ebetso ea Teko e Potlakileng ea Antigen ea SARS-CoV-2 (Colloidal Gold) e hlahisitsoeng ke k'hamphani ea rona e ke ke ea ameha.
