Fig. 2.

Temporal stability of transepithelial electrical properties and unidirectional anion fluxes across Con and A6KD Caco-2 monolayers 6–8 days postseeding in standard bicarbonate buffer. All open symbols in this figure represent Con monolayers and solid symbols signify A6KD monolayers. In the flux panels (C and D), circles represent mucosal-to-serosal flux (J_MS) and squares serosal-to-mucosal flux (J_SM). Short-circuit current (I_sc) is presented in A and transepithelial conductance (G_T) is shown in B; these parameters were obtained during the measurements of oxalate flux. C: unidirectional oxalate fluxes in Con (n = 9) and A6KD (n = 9) monolayers. D: comparison of unidirectional chloride fluxes in Con (n = 8) and A6KD (n = 8) monolayers. Horizontal bars at the bottom of the figure define the intervals that make up periods I and II (Per I and Per II), which are used throughout for statistical comparisons. Error bars represent ±1 SE.
