Recombinant SARS-COV-2 Spike RBD(Omicron XBB) Protein, His Tag

Description :
别名 S protein RBD; S glycoprotein RBD; Spike protein RBD Accession QHD43416.1 Recombinant SARS-CoV-2 Spike RBD (Omicron XBB) Protein is expressed from Expi293 with His tag at the C-terminal. It contains Arg319-Phe541(G339H, R346T, L368I, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, V445P, G446S, N460K, S477N, T478K, E484A, F486S, F490S, Q498R, N501Y, Y505H). 分子量 Approximately 26.21 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result. > 95% as determined by SDS-PAGE and HPLC. ELISA DataImmobilized SARS-CoV-2 Spike RBD (Omicron XBB) at 0.5g/ml (100l/well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 27.0ng/ml determined by ELISA. 内毒素 Lyophilized from 0.22m filtered solution in PBS (pH 7.4). 复溶 Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
