Spike Trimer (S1+S2) (B.1.617.2.1, Delta Plus Variant), His-Tag (SARS-CoV-2) Recombinant

• Description:

  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.1.617.2.1 also known as variant Delta Plus originally identified in India, and contains mutations T19R, G142D, R158G, K417N, L452R, T478K, D614G, P681R and D950N as well as deletion E156-F157.  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.
