Figure 4a, b, c. Permeability of polyamine-conjugated dendrimers across polarized Caco-2 cell monolayer in AB (apical-to-basolateral) and BA (basolateral-to-apical) directions at a concentration of 1μg/mL after incubation for different time intervals, a. 90 min; b. 150 min; c. 210 min.. Results are reported as mean ± standard error (S.E.M.) (n = 4 and p<0.05). (PAMAM-ORN: ornithine-conjugated PAMAM; PAMAM-ARG: arginine-conjugated PAMAM).

Permeability of polyamine-conjugated dendrimers across polarized Caco-2 cell monolayer in AB (apical-to-basolateral) and BA (basolateral-to-apical) directions at a concentration of 10 μg/mL after incubation for different time intervals, d. 90 min; e. 150 min; f. 210 min. Results are reported as mean ± standard error (S.E.M.) (n = 4 and p<0.05). (PAMAM-ORN: ornithine-conjugated PAMAM; PAMAM-ARG: arginine-conjugated PAMAM).
