Control and net P-gp uptakes of PFAS for (a, b) time- and (c) concentration-dependent kinetics at 1 min. Control and net BCRP uptakes for PFAS for (d, e) time- and (f) concentration-dependent kinetics at 1 min. The net uptake was obtained by subtracting uptakes in control vesicles from transporter vesicles. Each point represents mean ± SD of triplicates. All points are plotted with error bars; some are too small to see.
