Spike glycoprotein e teng ka holim'a novel coronavirus 'me e 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).

Viral nucleocapsid e entsoe ka nucleocapsid protein (N protein for short) le RNA. Protheine ea N e batla e tsitsitse, karolo e kholo ka ho fetisisa ea liprotheine tsa sebopeho sa kokoana-hloko le kutloisiso e phahameng ha e fumanoa.

Ho ipapisitsoe le likarolo tsa protheine ea N, Monoclonal antibody ea N protheine e khahlano le coronavirus e ncha e khethiloe molemong oa nts'etsopele le moralo oa lisebelisoa tsa rona tsa liteko tsa Antigen tse bitsoang "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" e reretsoeng ho lemoha boleng ba SARS-CoV-2 Antigen mefuteng ea nasal swab ea protheine ka har'a vitro.

Ke ho re, bakeng sa mofuta oa hona joale oa spike glycoprotein mutant joaloka 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 tlhahlobo e potlakileng ea SARS-CoV-2 Antigen Rapid (Colloidal Gold) e hlahisoang ke k'hamphani ea rona e ke ke ea ameha.
