Description 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.
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 104 kDa
Expressed Host HEK293 cells
Tag C-terminal Fc-Avi-tag Uniprot ID P0DTC2 SPIKE_WCPV
Storage Store at -80°C. Avoid freeze/thaw cycles.
Alternative Names SARS-CoV s1, coronavirus spike S1, covid, covid-19, covid19, coronavirus, 100719-1, 100719-2 Applications Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
