SARS-CoV-2 (2019-nCoV) Spike S1 NTD (L18F, D80A, D215G, LAL242-244 deletion, R246I) Protein (His Tag)

DESCRIPTION

A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike S1 NTD (YP_009724390.1, with mutations L18F, D80A, D215G, LAL242-244 deletion, R246I) (Met1-Ser305) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as 20C/501Y.V2 or B.1.351 lineage) which emerged in South Africa.

DETAILS
