Spike Trimer (S1+S2) (B.1.618 Variant), His-Tag (SARS-CoV-2)

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-CoV-2 Variant B.1.618, originally identified in India, and contains deletion 145/146YH as well as mutations E484K and D614G.  The construct also contains mutations 682RRAR685>A, K986P and V987P, and a T4 trimerization domain followed by a His-tag (6xHis) in C-terminal. The recombinant protein was affinity purified.
