Tissue distribution of Kir7.1-HA protein. Samples obtained from homozygous Kir7.1-HA mice (HA) or wild type mice (WT) were analyzed by western blot. Fractions of membranes obtained from eyes (n = 4), choroid plexus (n = 4), trachea (n = 3), lung (n = 10), ileum (n = 4), and jejunum (n = 4) are shown in (A). In (B) kidney plasma membrane fractions of cortex, inner (IM) and outer medulla (OM) are presented (n = 3). (C) Thin loops of Henle (TL) and collecting ducts (CD) were dissected from renal papillae and analyzed for the presence of aquaporin 1 (AQP1) and proton potassium pump (B1) as markers of TL and CD respectively (n = 5). Monoclonal rat anti-HA antibody was used in (A,B), while rabbit anti-HA antibody was used in (C). Ponceau red staining (A,B), or beta actin (C) were used as loading controls.
