Nonneutralizing human rhinovirus serotype 2-specific monoclonal antibody 2G2 attaches to the region that undergoes the most dramatic changes upon release of the viral RNA.
The monoclonal antibody 2G2 has been used extensively for detection and quantification of structural changes of human rhinovirus serotype 2 during infection. It recognizes exclusively A and B subviral particles, not native virus. We have elucidated the basis of this selectivity by determining the footprint of 2G2. Since viral escape mutants obviously cannot be obtained, the structures of complexes between Fab fragments of 2G2 and 80S subviral B particles were determined by cryoelectron microscopy. The footprint of the antibody corresponds to the capsid region that we predicted would undergo the most dramatic changes upon RNA release.
