Dose effect curves.

<p>Panel A and B represent the curves for HepG2 (▪) and Caco-2 (o), exposed to the least and most hydrophobic β-peptide (<i>#4</i> and <i>#16</i>, respectively) during 24 hours respectively. Panels C and D feature the behavior of Caco-2 and HepG2 correspondingly, for the three ACHC-containing β-peptides. The curves represent the mean of two independent experiments, each with four biological replicates. The error bars correspond to the standard error of the mean, where n = 8.
