SARS-CoV-2 Spike protein S1 subunit, receptor binding domain (RBD), also known as SARS-CoV-2 spike RBD, novel coronavirus spike RBD and nCoV spike RBD, GenBank Accession No. MN_908947.1, a.a. 319-541, fused at the C-terminus of the Fc portion of human IgG1, with a C-terminal Avi-tag, expressed in a HEK293 cell expression system and enzymatically biotinylated using Avi-tag™ technology. Biotinylation is confirmed to be ≥90% MW=54 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
