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

Figure 2 Kir6. 1 immunoreactivity in liver sections. Kir6.1 was expressed in hepatocytes and sinusoidal cells of the liver. A: Staining was intense in the area around the central vein; B: Showing punctate reactivity around the nucleus in hepatocytes cells and sinusoidal cells when viewing with high magnification; C: Weaker immunoreactivity was evident in the triangular areas of the vein and artery, but no reactivity was evident in the bile duct; D: A negative control section devoid of staining. a: Artery; Bd: Bile duct, Cv: Central vein; Pv: Portal vein. Bars: 100 µm (A and C), 20 µm (B), 50 µm (D).
