Biotinylated SARS-CoV-2 Spike S2 protein, His,Avitag™ (BA.2/Omicron)

Biotinylated SARS-CoV-2 Spike S2 protein, His,Avitag™ (BA.2/Omicron) (S2N-C82E4) is expressed from human 293 cells (HEK293). It contains AA Ser 686 - Pro 1213 (Accession # QHD43416.1 (N764K, D796Y, Q954H, N969K, F817P, A892P, A899P, A942P, K986P, V987P)). The spike mutations are identified on the SARS-CoV-2 Omicron variant (Pango lineage: BA.2/3/4/5). Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) are introduced to prevent the formation of aggregates in the course of protein production.
