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 South African Variant B.1.351 and contains mutations K417N, E484K and N501Y. It also contains a C-terminal His-tag. Note that the expected MW of the S1+S2 monomer is 136kDa. The recombinant protein is>=90% pure following high affinity Ni-NTA purification.
