Sample Request

Mfr.No.	100988-1
Immunogen Region	16-1213
Tag	C-terminal His-tag
Description	Recombinant SARS-CoV-2 Spike protein in its homotrimeric form, containing S1+S2 subunits and encompassing amino acids 16-1213. This protein contains three mutations: K417T, E484K and N501Y that have been found in emerging SARS-CoV-2 Variants of Concern and may lead to higher transmissibility and infectivity. This mutant Spike Trimer will be useful for structure-function studies, testing of neutralizing antibodies, or antibody and drug screening. The construct also contains a C-terminal His-tag. Note that the expected MW of the S1+S2 monomer is 136kDa but migrates at a higher MW in SDS-PAGE due to glycosylation. The recombinant protein is 90% pure following affinity purification.
Formulation	8 mM phosphate pH 7.4, 110 mM NaCl, 2.2 mM KCl, 20% glycerol
