Source

SARS-CoV-2 S1 protein, Fc Tag (S1D-C5256) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1). The mutations (L18F, D80A, D215G, LAL242-244del, R246I, K417N, E484K, N501Y, D614G) were identified in the SARS-CoV-2 variant (known as B.1.351 or 20C/501Y.V2) which emerged in the South Africa.
Predicted N-terminus: Val 1

Molecular Characterization

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 101.1 kDa. The protein migrates as 125-150 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 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
