STE73-2E9
An anti-RBD (SARS-CoV-2 Spike) antibody.
General information
STE73-2E9 is a human antibody which binds RBD of SARS-CoV-2 Spike protein at the RBD-ACE2 interface. Thereby, it neutralizes (as an IgG) SARS-CoV-2 infection in vitro. It was identified using phage display technique and originated in a SARS-CoV-2-naïve antibody library (Bertoglio et al., 2021).
