Wrapp et al. decided a 3.5-angstrom-resolution construction of the 2019-nCoV trimeric spike protein by cryo–electron microscopy. Using biophysical assays, the authors show that this protein binds no less than 10 occasions extra tightly than the corresponding spike protein of severe acute respiratory syndrome –CoV to their widespread host cell receptor. They also tested three antibodies recognized to bind to the SARS-CoV spike protein however didn’t detect binding to the 2019-nCoV spike protein. These studies provide useful data to information the event of medical counter-measures for 2019-nCoV.
