Spike S1 (16-685), Fc Fusion, Avi-tag (SARS-CoV-2) Recombinant

Severe acute respiratory Coronavirus 2 Spike Glycoprotein S1 (SARS-CoV-2 Spike S1), GenBank Accession No. QHD43416.1, a.a. 16-685, fused at the C-terminus of the Fc portion of human IgG1, with a C-terminal Avi-tag™, expressed in a HEK293 expression system, MW=104 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
