重组新冠病毒 (B.1.640.2) Spike RBD 蛋白 (His标签)(产品说明)
蛋白名称:SARS-CoV-2 (B.1.640.2) Spike RBD Protein (His Tag)
蛋白构建:A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutation R346S, N394S, Y449N, E484K, F490R, N501Y) (Arg319-Phe541) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant B.1.640.2).
表达宿主:HEK293 Cells
蛋白纯度:> 95 % as determined by SDS-PAGE. > 95 % as determined by SEC-HPLC.
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:Arg 319
蛋白分子量:The recombinant SARS-CoV-2 Spike RBD consists of 234 amino acids and predicts a molecular mass of 26.46 kDa. As a result of glycosylation, it migrates as an approximately 33.90 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号:YP_009724390.1
蛋白氨基酸序列:Arg319-Phe541
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.
