Study reveals how essential SARS-CoV-2 protein can be stabilized and scaled for production

A research group from the University of Texas in Austin described a high-yield production of a stabilized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S-protein) that may accelerate the development of vaccines and diagnostic tests. This methodological 'tour de force' paper is currently available on the bioRxiv* preprint server.
