Spike S1 RBD (B.1.1.7; Alpha Variant), Avi-His-Tag, Biotin-Labeled (SARS-CoV-2) HiP™ Recombinant

Recombinant SARS-CoV-2 Spike protein, RBD (Receptor Binding Domain) encompassing amino acids 319-541. This protein corresponds to SARS-CoV-2 Variant B.1.1.7, also known as variant Alpha originally identified in the United Kingdom, and contains mutation N501Y. It was constructed with a C-terminal Avi-Tag™ followed by a His-tag (6xHis) . The protein was enzymatically biotinylated using the Avi-Tag™ and affinity purified.HiP™indicates a high purity protein (≥90% pure) and less than 10% aggregation as measured by gel filtration.
