Lucifer yellow (452 Da) and dextran (20 kDa) fluorescence in the basolateral pole compartment of Caco-2/HT29-5M21 co-culture monolayer 21 days after the confluence. Basolateral pole compartment samples were analysed 30 to 180 minutes after permeability tracer addition into the apical compartment. Results are expressed as % of total fluorescence.
