Detection of Mitofusin-2 protein by Western Blotting. A specific Mitofusin-2 band at 86 kDa is observed in HELA cell lysate (A), A549 cell lysate (B), rat brain (C), rat heart (D), rat kidney (E), mouse brain (F), mouse heart (G), mouse kidney (H), mouse small intestine (I) and mouse NIH3T3 cell lysate (J). Samples were loaded at 50 µg total protein per lane. SDS-PAGE: denatured and reduced; Transfer Membrane: nitrocellulose; Blocking: 5% skim milk in TBS, 1.5 hours at RT; Primary antibody: overnight at 4°C (0.5 µg/mL); Secondary antibody: anti-rabbit-HRP (1/10,000) 1.5 hours at RT; Detection: Chemiluminiscence.
