义翘神州 SARS-CoV-2 Spike RBD (L452R, E484Q)蛋白 Fc标签 高纯度 新冠S蛋白

SARS-CoV-2 Spike RBD (L452R, E484Q) Protein (Fc Tag)（产品说明）
蛋白名称：SARS-CoV-2 Spike RBD (L452R, E484Q) Protein (Fc Tag)
蛋白构建：A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutations L452R, E484Q) (Arg319-Phe541) was expressed with the Fc region of human IgG1 at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant B.1.617, B.1.617.1 or B.1.617.3) which emerged in the India.
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 Spike RBD consists of 462 amino acids and predicts a molecular mass of 51.9 kDa. As a result of glycosylation, it migrates as an approximately 56.4 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-human IgG1-Fc
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.
