Recombinant SARS-CoV-2 Spike protein, RBD (Receptor Binding Domain) encompassing amino acids 319-541. This construct contains a C-terminal His-tag (6xHis) followed by an Avi-Tag. The protein was enzymatically biotinylated using the Avi-Tag and affinity purified.
Immunogen Region
319-541(end)
Tag
C-terminal His-Avi-Tag
Formulation
8 mM phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, 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.
