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

Figure 5 Immunoreactivity with SUR2A was evident in hepatocytes and sinusoidal cells (arrows) of the liver. A: Immunoreactivity with SUR2A was stronger in the area of the central vein (Cv) vs the border areas; B: Weaker immunoreactivity in the cell membrane and moderate immunoreactivity in the sinusoidal cells were observed (arrows); C: Weaker immunoreactivity with SUR2A was also observed in the endothelial cells of the blood vessels; D: Absorption negative control section devoid of staining (no more than background was observed). a: Artery. Cv: Central vein; Pv: Portal vein. Bars: 100 µm (A and C), 20 µm (B), 50 µm (D).
