Abstract
Fluorescence microscopy and fluorescent protein (FP)-tagged GLUT4 molecule have been great tools to characterize GLUT4 localization and dynamics inside the cell. However, it was difficult to distinguish GLUT4 storage vesicles (GSVs) from other intracellular compartments containing GLUT4 in live cells. Here, we describe the use of IRAP-pHluorin and total internal reflection fluorescence (TIRF) microscopy to selectively visualize GSVs and Rab proteins that associate with GSVs. This assay is also valuable to further defining GSV identity by unraveling other GSV-associated proteins.Entities:
