Ngoku i-XBB 1.5 eyahlukileyo iyaphambana phakathi kwehlabathi. Abanye abaxumi bayathandabuza ukuba uvavanyo lwethu olukhawulezayo lwe-covid-19 lwe-antigen luyakwazi ukubona oku kwahluka okanye hayi.

I-Spike glycoprotein ikhona kumphezulu wenoveli yekoronavirus kwaye iguqulelwe ngokulula njengokwahluka kweAlpha (B.1.1.7), ukwahluka kweBeta (B.1.351), ukwahluka kweGamma (P.1), ukwahluka kweDelta (B.1.617), ukwahluka kwe-Omicron (B.1.1.529), i-Omicron variant (XBB1.5) njalo njalo.
I-nucleocapsid yentsholongwane iqulethwe yi-nucleocapsid protein (i-N protein emfutshane) kunye ne-RNA. Iprotheyini ye-N izinzile ngokwentelekiso, eyona nxalenye inkulu kwiiprotheni zesakhiwo sentsholongwane kunye novakalelo oluphezulu ekubhaqweni.
Ngokusekwe kwiimpawu zeprotheyini ye-N, i-antibody ye-Monoclonal ye-N protein ngokuchasene noveli
i-coronavirus yakhethwa kuphuhliso kunye noyilo lwemveliso yethu ebizwa ngokuba yi "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" ejoliswe ekubhaqweni okusemgangathweni kwe-SARS-CoV-2 Antigen kwisampulu ze-swab zempumlo kwi-vitro ngokufunyanwa N protein.
Oko kukuthi, i-spike glycoprotein mutant strain yangoku kuquka i-XBB1.5 ayichaphazeli umphumo wovavanyo.
Ngoko ke, wethuSars-Cov-2 Antigeniyakwazi ukubona i-XBB 1.5
