Immunofluorescence as a Method to Study Golgi Organization in Larval Salivary Glands of Drosophila melanogaster.

Immunofluorescence is an important research tool in cell biology that reveals structural organization of subcellular organelles by detecting their associated constituents. Here, we describe an antibody staining method to detect Golgi-associated proteins in Drosophila larval salivary glands, using the cis-Golgi protein Lava lamp and the clathrin adaptor AP-1 as a suitable example. Golgi bodies immunostained using this protocol can be visualized using confocal or structured illumination microscopy.
