Histology (IMAGE) University of Pittsburgh Caption Multiple antibodies (green and red) bind SARS-CoV-2 spike protein within cells (blue) when there are no deletions (LEFT). Spike protein deletions stop neutralizing antibody from binding (absence of green) but other antibodies (red) still attach very well (RIGHT). Recurrent deletion generates variants that escape from neutralization.
