SARS-CoV-2 Spike S1 (Q52R, A67V, 69-70 deletion, 144 deletion, E484K, D614G, Q677H) Protein (His Tag)（产品说明）
蛋白名称：SARS-CoV-2 Spike S1 (Q52R, A67V, 69-70 deletion, 144 deletion, E484K, D614G, Q677H) Protein (His Tag)
蛋白构建：A DNA sequence encoding the SARS-CoV-2 Spike S1 (YP_009724390.1, with mutations Q52R, A67V, 69-70 deletion, 144 deletion, E484K, D614G, Q677H) (Met1-Arg685) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant B.1.525) which emerged in the Multiple countries.
表达宿主：HEK293 Cells
蛋白纯度：> 90 % as determined by SDS-PAGE.
蛋白活性：0
蛋白内毒素：< 1.0 EU per μg protein as determined by the LAL method.
预测N端：Val 16
蛋白分子量：The recombinant SARS-CoV-2 Spike S1 consists of 678 amino acids and predicts a molecular mass of 76.07 kDa. As a result of glycosylation, it migrates as an approximately 91.21 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号：YP_009724390.1
蛋白氨基酸序列：Met1-Arg685
蛋白标签：C-His
蛋白保存条件：Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
