Recombinant COVID-19 S-trimer Protein V2 (Omicron, B.1.1.529)
Recombinant COVID-19 S-trimer Protein V2 (Omicron, B.1.1.529) is produced by our mammalian expression system and the target gene encoding Cys15-Gln1208 is expressed with a 6His tag at the C-terminus. A67V, HV69-70del, T95I, G142D, VYY143-145del, N211del, L212I, ins214EPE, G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H, T547K, D614G, H655Y, N679K, P681H, N764K, D796Y, N856K, Q954H, N969K and L981F mutations were identified in the SARS-CoV-2 variant (known as Omicron/B.1.1.529 lineage) which emerged in South Africa. Six proline substitutions and furin cleavage site substitutions are introduced to stabilize the trimeric prefusion state of COVID-19 S protein and abolish the furin cleavage site, respectively.
