Heart lysates were prepared in RIPA buffer containing protease and phosphatase inhibitors. Heart lysate or cytoplasm and mitochondria fractions were loaded into 4–12%
Bis-Tris NuPAGE gels (ThermoFisher) or 4–15%
Mini Protean gels (Bio-Rad). Proteins were transferred to nitrocellulose membrane using
Turbo-blotter (Bio-Rad). Primary antibodies [
CaMKII (Abcam), 1:1000; phospho-
CaMKII (Thermo Scientific), 1:1000;
VDAC1 (Abcam), 1:2000;
FLAG (Rockland), 1:2000;
GAPDH (Cell Signaling), 1:10,000; CKmito (Sigma), 1:6000;
CoxIV (Cell Signaling), 1:1000; CK-M (Sigma), 1:10,000;
α-actinin (Sigma), 1:1000; OxPhos (Abcam), 1:500;
AcLys (Cell Signaling), 1:1000; HA (Sigma), 1:5000; SERCA2a (Badrilla), 1:5000; PDH (Abcam), 1:1000] were incubated with the membrane overnight at 4 °C. Secondary antibodies were incubated with the membrane at room temperature for 1 h. Blots were imaged using an
Odyssey Fc Imager (Licor). Bands were quantified using
Image Studio Software (Licor), coomassie-stained membranes were quantified using Image J software.
