Source
SARS-CoV-2 Spike S1, His Tag (S1N-C52Hu) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1). The mutations (T19R, G142D, EF156-157del, R158G, L452R, T478K, D614G, P681R) were identified in the SARS-CoV-2 Delta variant (Pango lineage: B.1.617.2; other names: 21A/S:478K).
Predicted N-terminus: Val 16
Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 76.7 kDa. The protein migrates as 100-120 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.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
