Extra Details:: SARS-CoV-2 S protein, His Tag (SPN-C52Hg) is the ectodomain of SARS-CoV-2 S protein that contains AA Val 16 - Pro 1213 (Accession # QHD43416.1) and mutations, which have become increasingly common in SARS-CoV-2 viruses from around the world. The recombinant protein is expressed from human 293 cells (HEK293) 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. The L18F/ T20N/ P26S/ D138Y/ R190S/ K417T/ E484K/ N501Y/ D614G/ H655Y/ T1027I/ V1176F mutations were identified in the SARS-CoV-2 Gamma variant (Pango lineage: P.1; other names: 20J/501Y.V3).
