Comparison of uptake of different PNP 45 [[4]] and PNP 90 in NR8383 and Caco-2 cells (1 μg/ml) as % of unperturbed uptake upon 24 h exposure after blocking the endocytotic uptake (n = 5) at 4 ºC or by a mixture of 2-deoxyglucose and sodium azide. The * sign signifies p < 0.05 compared to unperturbed uptake.
