Figure 2.
Effects of verapamil on the transport of HCPT from the apical to basolateral side or the opposite direction, Caco-2 cell monolayers were incubated at 37 °C in HBSS (pH 7.4), and HCPT (2 µM) were added to the apical or basolateral side, verapamil were also added to the donor chamber with HCPT. *Significant differences (p < 0.05) were seen compared to the control sample. Each point represents the mean ± SD of 3 determinations.
