    产品描述

    Recombinant SARS-COV-2 Spike S1(Deltacron) Protein is expressed from HEK293 with His tag at the C-terminal.It contains Gln14-Arg683(T19R, A27S, T95I, G142D, EFR156G, NL211I, INS214EPE, G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H, T547K, D614G, H655Y, N679K, P681H). Alanine substitutions (R683A) are introduced to stabilize the trimeric prefusion state of SARS-COV-2 Spike S1(Deltacron) Protein and abolish the furin cleavage site, respectively.
