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 United Kingdom Variant B.1.1.7. It contains mutations N501Y, A570D, D614G, P681H, T716I, S982A, D1118; deletions: 21765:6 (69-70HV), 21991:3 (44Y). This construct 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.
