Source
 
Biotinylated SARS-CoV-2 S protein RBD, His,Avitag (SPD-C82E8) is expressed from human 293 cells (HEK293).
Predicted N-terminus: Arg 319
 
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 28.2 kDa. The protein migrates as 33-35 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

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.
