This variant, also known as 501Y.V2, has many mutations which may lead to higher transmissibility and infectivity. In particular, the B.1.351 variant contains three mutations within the RBD region of the Spike S1 protein: K417N, E484K, and N501Y. Investigating the effect of mutations on viral replication and pathogenesis will be critical for developing effective strategies for vaccines and antibody therapies against COVID-19.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eRecombinant Protein\u003c\/span\u003e\n\u003cp\u003eRecombinant Spike S1 (B.1.351 SARS-CoV-2 protein is produced using a validated recombinant expression system and supplied in aqueous buffer solution.
