Source

SARS-CoV-2 Spike Trimer, His Tag (SPN-C52Hh) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Pro 1213 (Accession # QHD43416.1). The mutations (P26S, HV69-70del, V126A, Y144del, LLA241-243del, H245Y, S477N, E484K, D614G, P681H, T1027I, D1118H) were identified in the SARS-CoV-2 variants which emerged in Europe (known as B.1.620). Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) and alanine substitutions (R683A and R685A) are introduced to stabilize the trimeric prefusion state of SARS-CoV-2 S protein and abolish the furin cleavage site, respectively.
Predicted N-terminus: Val 16

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 137.5 kDa. The protein migrates as 160-200 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS. Normally trehalose is added as protectant before lyophilization.
