Perinuclear GLUT4 and β-COP staining do not overlap. Immunofluorescence of 3T3-L1 adipocytes stained for GLUT4 (red) and β-COP (green) was performed and optical cross-sections were acquired by deconvolution microscopy. The images shown are the center cross-sections from the reconstructed stack of images. GLUT4 staining is shown in a and d; β-COP staining is shown in b and e. Merged images are shown in c and f. a–c show staining of unstimulated 3T3-L1 adipocytes, and d–f show staining of insulin-stimulated 3T3-L1 adipocytes. Bar, 10 μm.
