Recombinant SARS-CoV-2 Spike protein S1 subunit, encompassing amino acids 16-685. This protein corresponds to SARS-CoV-2 Variant B.1.618 originally identified in India, and contains deletions Y145 and H146 as well as mutations E484K and D614G. It was constructed with a C-terminal Avi-Tag followed by a His-tag (6xHis). The protein was affinity purified. Constructs: Spike S1 (B.1.618 Variant) (16-685-Avi-His) (SARS-CoV-2)
