Source
SARS-CoV-2 S1 protein NTD (A222V), His Tag (S1D-C52H8) is expressed from human 293 cells (HEK293). It contains AA Ser 13 - Leu 303 (Accession # QHD43416.1(A222V)).
Predicted N-terminus: Ser 13
Molecular Characterization
Online(Ser 13 - Leu 303 ) QHD43416.1 (A222V)Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 34.9 kDa. The protein migrates as 45-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method.
Purity
>90% 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.
Contact us for customized product form or formulation.
Reconstitution
