Description
BACKGROUND The ability to visualize organelle localization and dynamics is very useful in studying cellular physiological events. Until recently, this has been accomplished using a variety of staining methods. However, staining can give inaccurate information due to nonspecific staining, diffusion of the stain or through toxic effects. The ability to target green fluorescent protein (GFP) to various organelles allows for specific labeling of organelles in vivo. GFP is a jellyfish Aequorea victoria protein composed of 238 amino acid residues (26.9kDa).1 It exhibits bright green fluorescence when exposed to blue light. When introduced into eukaryotic cells, GFP gene produces a fluorescent protein without the need for exogenous substrates or cofactors. GFP fluorescence is stable under fixation conditions and suitable for a variety of applications. The GFP-tagged genes now provide a powerful and more direct visual demonstration of the localization of the fusion protein.2 GFP can also be used for other studies including protein-protein interaction by fluorescence energy transfer (FRET) assay.
