Spike glycoprotein dị n'elu coronavirus ọhụrụ ma gbanwee ngwa ngwa dịka Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) na Omicron (B.1.1.529, BA.2, BA.4, BA.5).

Nucleocapsid nke nje ahụ nwere protein nucleocapsid (N protein dị mkpụmkpụ) na RNA. Protein N ahụ kwụsiri ike, nke kachasị na protein ndị dị n'ime nje ahụ ma nwee nnukwu mmetụta na nchọpụta.

Dabere na njirimara nke protein N, ahọpụtara monoclonal antibody nke protein N megide coronavirus ọhụrụ na mmepe na nhazi nke ngwa nnwale Antigen anyị nke akpọrọ "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" nke e mere maka nchọpụta nke SARS-CoV-2 Antigen na ihe nlele imi na vitro site na nchọpụta nke protein N.

Nke ahụ pụtara, maka ụdị glycoprotein mutant dị elu ugbu a dịka Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) na Omicron (B.1.1.529, BA.2, BA.4, BA.5). Arụmọrụ nke SARS-CoV-2 Antigen Rapid Test (Colloidal Gold) nke ụlọ ọrụ anyị mepụtara agaghị emetụta ya.
