Source
Biotinylated SARS-CoV-2 S1 protein, His,Avitag (S1N-C82E9) is expressed from human 293 cells (HEK293).
Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 78.6 kDa. The protein migrates as 100-150 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Biotinylation
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Biotin:Protein Ratio
The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
Endotoxin
Less than 1.0 EU per μg by the LAL method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Supplied as 0.2 μm filtered solution in 10 mM PB, pH7.4.
