Localization of ATP-sensitive K+ channel subunits in rat liver

Figure 11 Immunofluorescence double staining for ATP-sensitive K⁺ channel subunits Kir6. 1, Kir6.2, SUR1, SUR2A and SUR2B with CD68 in liver sections. Immunofluorescence double staining for ATP-sensitive K⁺ channel subunits Kir6.1 (A), Kir6.2 (D), SUR1 (G), SUR2A (J) and SUR2B (M) with CD68 (B, E, H, K, and N, marker of Kupffer cells) in liver sections; Some CD68⁺ cells (Kupffer cells) colocalized with Kir6.1 (C, arrows) and/or Kir6.2 (F, arrows), but most colocalized with SUR1 (I, arrows), SUR2A (L, arrows) and SUR2B (O, arrows).
