Imaging green fluorescent protein fusions in living fission yeast cells.
The use of green fluorescent protein (GFP) fusions as biosensors for examining protein localization and dynamics has revolutionized cell biology. Here, we describe the methods developed for imaging of GFP-fusions in the fission yeast Schizosaccharomyces pombe using fluorescence microscopy, with a focus on the use of time-lapse imaging to analyze the dynamics of microtubules. We discuss the considerations in fluorescence microscopy, cell preparation, data acquisition, and image analysis appropriate for analysis of living cells.
