Coronavirus spike重组蛋白|Recombinant SARS-COV-2 FL.1.5.1 (Omicron) Spike RBD Protein (aa319-529, His Tag)（产品说明）
蛋白名称：SARS-COV-2 FL.1.5.1 (Omicron) Spike RBD Protein (aa319-529, His Tag)(HPLC-verified)
蛋白构建：A DNA sequence encoding the SARS-CoV-2 (FL.1.5.1) Spike RBD (YP_009724390.1, with mutation G339H, R346T, L368I, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, V445P, G446S, F456L, N460K, S477N, T478R, E484A, F486P, F490S, Q498R, N501Y, Y505H) (Arg319-Lys529) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant FL.1.5.1).
表达宿主：HEK293 Cells
蛋白纯度：≥ 90 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.
蛋白活性：Immobilized Recombinant Human ACE2 / Angiotensin-Converting Enzyme 2 Protein (Fc Tag) (Cat: 10108-H05H) at 2 μg/mL (100 μL/well) can bind Recombinant SARS-COV-2 FL.1.5.1 (Omicron) Spike RBD Protein (aa319-529, His Tag) (Cat: 40592-V08H154), the EC50 is 4-12 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 (FL.1.5.1) Spike RBD consists of 222 amino acids and predicts a molecular mass of 25.22 kDa. As a result of glycosylation, it migrates as an approximately 34.2 kDa band in SDS-PAGE under reducing conditions.
