Description Severe acute respiratory Coronavirus 2 Spike Glycoprotein S1 Receptor Binding Domain (SARS-CoV-2 Spike S1 RBD), also known as novel coronavirus spike S1 RBD and nCoV spike S1 RBD, GenBank Accession No. QHD43416.1, a.a. 319-541, with a C-terminal mouse Fc-tag (mFc), expressed in a HEK293 cell expression system. MW=50 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
Formulation Aqueous buffer solution. 8 mM Phosphate, pH 7.4, 110 mM NaCl, 2.2 mM KCl, and 20% glycerol.
Species SARS-COV-2
Calculated MW 50 kDa
Expressed Host HEK293 cells
