Purity: Greater than 95% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/ug as determined by LAL method. Biological Activity: Loaded 2019-nCoV S Protein RBD-mFc on AMC Biosensor, can bind Human ACE-2-His with an affinity constant of 2.06 nM as determined in BLI assay. Form: Liquid. Buffer: 0.2 µm filtered 20 mM Tris, 300 mM NaCl, 1 mM ZnCl2, 10% Glycerol, pH 7.4. Reconstitution: n/a. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: n/a. Reference: n/a. Function: nan
