Spike glycoprotein wuxuu ku jiraa dusha sare ee fayraska cusub waxaana si fudud isu beddesha 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-ka fayrasku wuxuu ka kooban yahay borotiinka nucleocapsid (N protein marka la soo gaabiyo) iyo RNA. Borotiinka N waa mid deggan, waana saamiga ugu weyn ee borotiinnada qaab-dhismeedka fayraska iyo xasaasiyad sare oo lagu ogaan karo.

Iyada oo lagu saleynayo sifooyinka borotiinka N, unugyada difaaca jirka ee Monoclonal ee borotiinka N ee ka dhanka ah coronavirus-ka cusub ayaa lagu doortay horumarinta iyo naqshadeynta qalabkayaga tijaabada Antigen-ka ee is-tijaabinta oo loogu magac daray "Tijaabada Degdegga ah ee Antigen-ka ee SARS-CoV-2 (Dahabka Colloidal)" kaas oo loogu talagalay in lagu ogaado tayada SARS-CoV-2 Antigen-ka ee muunadaha suufka sanka ee in vitro iyada oo loo marayo ogaanshaha borotiinka N.

Taas macnaheedu waa, nooca glycoprotein-ka ee hadda soo koraya 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 Tijaabada Degdegga ah ee SARS-CoV-2 Antigen (Colloidal Gold) ee ay soo saarto shirkaddayadu saameyn kuma yeelan doonto.
