Deletion of Cldn3 does not alter absolute permeabilities for Pi, Ca²⁺, Na⁺, and Cl⁻ in the ileum of mice fed on high Pi. Ion permeabilities were calculated from diffusion potential and transepithelial resistance measured with the electrical Ussing chamber technique. Absolute permeabilities for A Na⁺, B Cl⁻, C Pi, and D Ca²⁺ are shown for apical (top) and basolateral (bottom) solution exchange, respectively. N = 6 mice per group. A–D Unpaired t-test
