Larger Image Figure 6. Comparison of the effects of PREGS on Kir1.1, Kir2.1, Kir2.2, Kir2.3, and Kir3 channels expressed in Xenopus oocytes.The magnitudes of change in Kir currents by 100 µM PREGS were normalized to the 3 mM Ba2+-sensitive current components. For Kir3 channels, oocytes expressing brain-type Kir3.1/Kir3.2 channels were used. Current responses were measured at a membrane potential of −70 mV in an hK solution containing 96 mM K+. Data are expressed as mean±SEM. Image published in: Kobayashi T et al. (2009) Kobayashi et al. Creative Commons Attribution license Permanent Image Page Printer Friendly View XB-IMG-124002
