(A) A differentiated Caco-2 Monolayer was incubated with fluorescence labeled P31–43 or P56–68 on the apical side of the cells. (B) After 3 h or 24 h incubation the apical and basal cell media were analyzed by fluorescence spectroscopy and MALDI-TOF-MS. The Caco-2 cells were analyzed by flow cytometry and confocal microscopy.
