Monoclonal antibody-resistant mutants selected with a respiratory syncytial virus-neutralizing human antibody Fab fragment (Fab 19) define a unique epitope on the fusion (F) glycoprotein
A recombinant human antibody fragment, designated RSV Fab 19, efficiently neutralizes respiratory syncytial virus (RSV), Here we report the results of our sequence analysis of antibody escape mutants that identified F glycoprotein amino acids critical for binding of human or murine RSV F-neutralizing antibodies.
