重组新冠病毒(BA.2.12.1) Spike RBD 蛋白 (His标签), 生物素标记(产品说明)
蛋白名称:SARS-CoV-2 (BA.2.12.1) Spike RBD Protein (His Tag), Biotinylated
蛋白构建:A DNA sequence encoding the SARS-CoV-2 (BA.2.12.1) Spike RBD (YP_009724390.1, with mutations G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, L452Q, S477N, T478K, E484A, Q493R, Q498R, N501Y, Y505H)(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 BA.2.12.1). The purified protein was biotinylated in vitro.
表达宿主:HEK293 Cells
蛋白纯度:> 95 % 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:Arg 319
蛋白分子量:The recombinant SARS-CoV-2 (BA.2.12.1) Spike RBD consists of 234 amino acids and predicts a molecular mass of 26.72 kDa. As a result of glycosylation, it migrates as an approximately 37.06 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.
