义翘神州 SARS-CoV-2 Spike S1+S2蛋白 B.1.617.2变种 生物素化 新冠S蛋白

SARS-CoV-2 Spike S1+S2 (157-158 deletion, T19R, G142D, E156G, L452R, T478K, D614G, P681R, D950N) Protein (ECD, His & AVI Tag), Biotinylated（产品说明）
蛋白名称：SARS-CoV-2 Spike S1+S2 (157-158 deletion, T19R, G142D, E156G, L452R, T478K, D614G, P681R, D950N) Protein (ECD, His & AVI Tag), Biotinylated
蛋白构建：A DNA sequence encoding the SARS-CoV-2 Spike S1+S2 (YP_009724390.1, with mutations 157-158 deletion, T19R, G142D, E156G, L452R, T478K, D614G, P681R, D950N) (Met1-Pro1213) was expressed with a c-terminal polyhistidine tagged AVI tag at the C-terminus. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. The mutations were identified in the SARS-CoV-2 variant (known as B.1.617.2) which emerged in the India.
