SARS-CoV-2 Spike RBD (L452R, T478K) Protein (His & AVI Tag), Biotinylated from Sino Biological, Inc.

A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutations L452R, T478K) (Arg319-Phe541) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The purified protein was biotinylated in vitro. The mutations were identified in the SARS-CoV-2 variant (known as variant B.1.617.2) which emerged in the India
