Materials and MethodsWe utilised INS-1 cells (passage 200) for electrophysiology, Western blot evaluation, and immunocytochemistry experiments.Streptavidin INS-1 cells were cultured on poly-L-lysine oated coverslips in RPMI-1640 medium containing 10 (vol/vol) FBS and 11 mM D-glucose. Adjustments inside the surface level of KATP channels have been detected by surface biotinylation/streptavidin purification and subsequent Western blot evaluation utilizing anti-Kir6.two antibody (Santa Cruz Biotechnology). Specificity for anti-Kir6.2 was examined making use of siKir6.two transfected cells (Fig. S8). AMPK activation was detected by a industrial ELISA kit (Invitrogen) or by Western blot analysis using phosphorylationspecific antibodies to AMPK at Thr172 (pAMPK) and its substrate, pACC, from Cell Signaling Technologies. Complete scans of all Western blots indicating regions shown inside the respective key figures are shown in Fig. S9. Immunofluorescence analysis was performed making use of pancreatic tissue sections and isolated pancreatic islets obtained from female C57BL/6 WT and ob/ob mice at age 7 wk (Shizuoka, Japan), too as INS-1 cells. Information regarding antibodies utilised within the present study is offered in Tables S1 and S2. All animal experimental procedures had been performed in accordance with all the recommendations in the University Committee on Animal Sources at Seoul National University (approval no. SNU-120216-02). Confocal images have been obtained employing a FluoView 1000 (Olympus) or TCS-SP2 (Leica) confocal microscope and processed with Leica Confocal Application.
