Source

SARS-CoV-2 S1 protein CTD, His Tag (MALS-verified) (S1D-C52H3) is expressed from human 293 cells (HEK293). It contains AA Asn 334 - Pro 527 (Accession # QHD43416.1).
Predicted N-terminus: Asn 334

Molecular Characterization

Online(Asn 334 - Pro 527) QHD43416.1Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 23.6 kDa. The protein migrates as 28-30 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,pH7.3 . Normally trehalose is added as protectant before lyophilization.
