Recombinant SARS-CoV-2 Spike protein in its homotrimeric form, containing S1+S2 subunits and encompassing amino acids 16-1213. This protein corresponds to SARS-CoV2 Variant P.1 originally discovered in Brazil and contains 11 mutations in addition to 682RRAR685>A, K986P and V987P, as listed below. 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 high affinity Ni-NTA purification.
