Fig. 1From: Comparison of immune response to human rhinovirus C and respiratory syncytial virus in highly differentiated human airway epithelial cellsImmunofluorescence of differentiated HBE cells. The differentiated HBE cells were fixed, followed by incubation with mouse monoclonal anti-β tubulin antibody (red, A), mouse Muc5AC monoclonal antibody (green, B), or monoclonal anti-ZO-1 antibody (red, C). Confocal images were taken with a magnification of 200× for A and B, and 360× for C. Nuclei were stained with DAPI. Scale bars, 20 μmBack to article page
