Proteins & Peptides

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.1.617.1 also known as variant Kappa originally identified in India, and contains mutations G142D, E154K, L452R, E484Q, D614G, P681R and Q1071H. 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.

Recombinant human IL2RG (interleukin 2 receptor subunit gamma) encompassing amino acids 23-262. This construct contains a C-terminal Avi-Tag™ followed by a His-Tag (6xHis). The recombinant protein was enzymatically biotinylated using the Avi-Tag™ and affinity purified.
