Key Properties

• Expression System: HEK293 Cells
• Biological Origin: SARS-CoV-2
• Biological Activity: SARS-COV-2 XBB.1 (Omicron) Spike RBD Protein (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with His and Avi tag. The predicted molecular weight is 28.38 kDa and the accession number is YP_009724390.1.
• Tag: C-His-Avi
• Expression Region: A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutation G339H, R346T, L368I, S371F, S373P, S375F, T376A, D405N, R408S, N440K, V445P, G446S, N460K, S477N, T478K, E484A, F486S, F490S, Q498R, N501Y, Y505H) (Arg319-Phe541) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. The mutations were identified in the SARS-CoV-2 variant (known as variant XBB.1). Predicted N terminal: Val 16
• MW: 28.38 kDa (predicted); 37.8 kDa (reducing condition, due to glycosylation)
• Purity: 98.00%
