Key Properties

• Expression System: HEK293 Cells
• Biological Origin: SARS-CoV-2
• Biological Activity: SARS-CoV-2 BA.2.75 (Omicron) Spike RBD Protein (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with His and Avi tag. The predicted molecular weight is 28.56 kDa and the accession number is YP_009724390.1.
• Tag: C-His-Avi
• Expression Region: A DNA sequence encoding the SARS-CoV-2 (BA.2.75) Spike RBD (YP_009724390.1, with mutation G339H, S371F, S373P, S375F, T376A, D405N, R408S, K417N, N440K, G446S, N460K, S477N, T478K, E484A, Q498R, N501Y, Y505H) (Arg319-Phe541) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The mutations were identified in the SARS-CoV-2 variant (known as variant BA.2.75). The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. Predicted N terminal: Arg 319
• MW: 28.56 kDa (predicted); 34.72 kDa (reducing condition, due to glycosylation)
• Purity: 98.00%
