Recombinant SARS-CoV-2 Spike protein, S1 subunit encompassing amino acids 16-685. The construct contains a C-terminal Avi-Tag followed by a His-tag (6xHis). The recombinant protein was affinity purified and enzymatically biotinylated using the Avi-Tag.
Immunogen Region
16-685
Tag
C-terminal Avi-His-Tag
Formulation
8 mM phosphate pH 7.4, 110 mM NaCl, 2.2mM KCl, and 20% glycerol.
Species
SARS-CoV-2
Notes
This protein runs at a higher MW by SDS-PAGE due to glycosylation. This protein is enzymatically biotinylated using Avi-Tag technology. Biotinylation is confirmed to be>=90%. Avoid freeze/thaw cycles.
