Fig 6. Ankyrin B and ankyrin G expression in cortex and medulla.

(A&B) Immunofluorescent micrographs of ankyrin and α1-Na,K-ATPase in renal cortex and medulla. Both ankyrin B and G are found on both apical and basolateral membrane of tubule cells. Ankyrin G is widely distributed, but tapers in the medulla and DCT. Ankyrin B is enriched in the medullar kidney, especially in the distal tubule and collecting duct.
