蛋白名称:新冠病毒N501Y突变体蛋白
蛋白构建:A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike RBD(N501Y)-His Recombinant Protein (YP_009724390.1) (Arg319-Phe541(N501Y)) was expressed with a polyhistidine tag at the C-terminus.
表达宿主:HEK293 Cells
蛋白纯度:> 95 % as determined by SDS-PAGE.
蛋白活性:Measured by its binding ability in a functional ELISA. Immobilized human ACE2 protein (mFc tag)(Cat: 10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 (2019-nCoV) Spike RBD(N501Y)-His(40592-V08H82), the EC50 of SARS-CoV-2 (2019-nCoV) Spike RBD(N501Y)-His (40592-V08H82) is 3-20 ng/mL.
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 (2019-nCoV) Spike RBD(N501Y)-His Recombinant Protein consists of 234 amino acids and predicts a molecular mass of 26.6 kDa. As a result of glycosylation, it migrates as an approximately 35 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号:YP_009724390.1
蛋白氨基酸序列:Arg319-Phe541(N501Y)
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.

摘要 基因重组蛋白在大肠杆菌中表达时,由于表达量高,往往形成无生物活性的包涵体。包涵体必须经过变性和复性的过程才能获得有活性的重组蛋白。如何提高基因重组蛋白质的复性率,是生物工程技术的一个研究热点。对近年来的重组蛋白质的复性方法做一评述,为研究蛋白质折叠以及复性技术的进一步应用提供依据。 关键词 重组蛋白 包涵体 复性 二硫键 到目前为止,人们表达的重组蛋白质已有4000多种,其中用E.coli表达的蛋白质要占90%以上,尽管基因重组技术为大规模生产目标蛋白质提供
