Description |
Coronavirus S proteins contain two subunits, called S1 and S2, which are separated by a protease-sensitive amino acid sequence. S1 determines the specificity of receptor binding, while S2 mediates membrane fusion and virus entry. Biosensis SARS-CoV-2 Spike Protein S1 Receptor-Binding Domain (S1RBD) protein is an E. coli expressed, recombinant protein fragment designed for research scientific study of the SARS-CoV-2 virus and the COVID-19 disease it causes. |
