Biotinylated Recombinant SARS-CoV-2 Spike Trimer Protein (T19R, V70F, FR157-158Del, A222V, W258L, K417N, L452R, T478K, D614G, P681R, D950N) (aa 16-1213) [His & Avi]

Expressed from HEK293 Cells with T4 fibritin trimerization motif and a polyhistidine tag at the C-terminus. Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) and alanine substitutions (R683A and R685A) are introduced to stabilize the trimeric prefusion state of SARS-CoV-2 S protein and abolish the furin cleavage site, respectively.
