Values from model independent experiments are the mean of 5 separate occasions in both transport directions from n = 2 to 3 filters per occasion for a total of 13 filters for each transport direction. Abbreviations: CV is coefficient of variation obtained from model independent analysis, RSE is the relative standard error of the estimate of the model-based parameter estimate; BOFV is between occasion and filter variability expressed as %; RUV is residual unexplained variability for apical (top) and basolateral (bottom) compartment CDF concentrations, respectively, expressed as %.
