Transcytosis of 5H7-IgA and 5H7-IgG antibodies across polarized Vero-IgR monolayers. In the two-chamber transwell system with polarized Vero-IgR monolayers, 20 μg of 5H7-IgA or 5H7-IgG antibodies in 100 μl of medium was added to the basal chamber, and the transported IgA antibodies in the apical chamber were quantified at 6, 12, 18, 24, 30, 36, 42, and 48 h after the application of antibodies.
