mAb Beta-22
An anti-SARS-CoV-2 monoclonal antibody.
General information
mAb Beta-22 is a monoclonal antibody neutralizing SARS-CoV-2 identified in a memory B cell of a COVID-19 convalescent patient who had been infected with the Beta variant of SARS-CoV-2 (Liu et al., 2022). mAb Beta-22 neutralizes Omicron variant in vitro (Dejnirattisai et al., 2022). It also neutralizes the Gamma variant but has reduced or no activity against the strains Alpha and Delta (is K417N/T-dependent) (Liu et al., 2022).
