Abstract
Described herein are synthetic monoclonal antibodies, built on a human IgG framework, e.g., Trastuzumab, that bind to the spike protein of SARS-CoV-2 (the causative agent of COVID-19), compete for ACE2 binding, and potently inhibit SARS-CoV-2 infection and proliferation. The antibodies that exhibit neutralization potencies at sub-nanomolar concentrations against SARS-CoV-2/USA/WA1 in Vero E6 cells are bound to the receptor binding domain (RBD).
