Serum K⁺ in control mice and mice with intercalated cell-specific Rhbg deletion (IC-Rhbg-KO) on regular and K⁺-free diet. Scatterplot of serum K⁺ measurements in mice with intact Rhbg expression (Cre−) and with IC-Rhbg-KO (Cre+) on normal diet and after 3 days of K⁺-free diet. K⁺-free diet decreased serum K⁺ concentration significantly in both genotypes. Serum K⁺ did not differ significantly between mice with intact Rhbg expression and those with IC-Rhbg-KO, either on normal diet or after 3 days of K⁺-free diet.
