According to the latest research，there are many mutant strains of the Covid-19 virus, which are the British variants (VOC202012/01, B.1.1.7 or 20B/50Y.V1). There are 4 mutation points on the nucleoprotein, which are located at D3L, R203K, G203R and S235F. South Africa variants (501.V2, 20C/501Y.V2 or B.1.315) do not have any mutation points on the nucleoprotein .The new Indian variants have nucleoprotein mutation points located at P6T, P13L and S33I as bellows pictures:
We, hangzhou testsea here solemnly declare that Covid-19 tests which we produce use nucleoprotein monoclonal antibodies for detection,recognition epitopes which the corresponding antigen are located in N47-A173 (NTD region), as a result, our tests are qualified for these virus variants.
