The screening yielded eight antibodies that can bind to the SARS-CoV-2 spike glycoprotein – a pyramid-shaped structure on the viral surface, composed of proteins with attached carbohydrates, that facilitates entry into the host cell. Multiple studies have suggested that the spike glycoprotein is the main target for both neutralizing antibodies and vaccines, and vaccines currently in development use a piece of this structure to prime the immune system. Further tests narrowed the field to reveal one SARS-CoV antibody, called S309, that successfully neutralizes SARS-CoV-2. https://scienceblog.com/516449/x-ray-experiments-zero-in-on-covid-19-antibodies/
