SARS-CoV-2 (2019-nCoV) Spike S1 (L18F, D80A, D215G, LAL242-244 deletion, R246I, K417N, E484K, N501Y, D614G) Protein (His Tag)(产品说明)
蛋白名称:新冠病毒Spike S1 (L18F, D80A, D215G, LAL242-244 deletion, R246I, K417N, E484K, N501Y, D614G) 重组蛋白 (His Tag)
蛋白构建:A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike S1 (YP_009724390.1, with mutations L18F, D80A, D215G, LAL242-244 deletion, R246I, K417N, E484K, N501Y, D614G) (Met1-Arg685) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as 20C/501Y.V2 or B.1.351 lineage) which emerged in South Africa.
表达宿主:HEK293 Cells
蛋白纯度:> 90 % as determined by SDS-PAGE.
蛋白活性:检测中
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 (2019-nCoV) Spike S1 consists of 678 amino acids and predicts a molecular mass of 76 kDa. As a result of glycosylation, it migrates as an approximately 106.3 kDa band in SDS-PAGE under reducing conditions.
