| SARSCoV2 Spike Trimer Protein, His Tag (NB.1.8.1) (SPNS522b) is expressed from human 293 cells (HEK293). It contains AA Val 16 Pro 1213 (Accession QHD43416.1 (T19I, R21T, T22N, A27S, S50L, F59S, V127F, G142D, F157S, R158G, G184S, L212I, V213G, L216F, H245N, A264D, I332V, G339H, K356T, S371F, S373P, S375F, T376A, R403K, D405N, R408S, K417N, A435S, N440K, V445H, G446S, N450D, L452W, L455S, F456L, N460K, S477N, T478I, N481K, E484K, F486P, Q493E, Q498R, N501Y, Y505H, E554K, A570V, D614G, P621S, H655Y, N679K, P681R, N764K, F817P, A892P, A899P, A942P, K986P, V987P, D796Y, S939F, Q954F, N969K, P1143L)). The recombinant protein is expressed from human 293 cells (HEK293) with T4 fibritin trimerization motif and a polyhistidine tag at the Cterminus. Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) are introduced to stabilize the trimeric prefusion state of SARSCoV2 S protein. - Proteine/Peptide |
