Tissue localization of KCNE1 and KCNQ1 expression. (A) RT-PCR analysis of KCNE1 and KCNQ1 mRNA in the kidneys, colon, and adrenal glands of wild-type mice. (B) In situ hybridization analysis of KCNE1 mRNA in the zona glomerulosa of toluidine blue counterstained adrenal sections of wild-type mice. No signal is detected in sections from kcne1−/− mice (data not shown).
