Fig. 3. Sarcolemmal K_ATP channel subunits, Kir6.2 and SUR2A, co-localize with LDH in cardiomyocytes. Original images of rod-shaped and rounded cardiomyocytes stained with either anti-Kir6.2 or anti-SUR2A or anti-Kv 1.3 and anti-LDH antibodies labelled with rhodamine (red channel) or fluorescein (green channel) as indicated in the figure. Yellow colour is suggestive of co-localization. Scale bar, 45 µm.
