Abstract
In studies of eukaryotic cell cycle regulation, the budding yeast Saccharoymyces cerevisiae offers many advantages as a model system. Due to its simple growth requirements and genetic tractability, this organism is a powerful tool for investigating the molecular regulation of cell cycle control. One earlier disadvantage to performing cell cycle analyses in yeast was that existing methods were restricted to either visual analysis or flow cytometry, both of which present limitations in the scope and accuracy of the data obtained. This unit demonstrates the combined use of DNA content measurements and bright-field image analysis using multispectral imaging flow cytometry (MIFC) to provide a more precise quantitation of yeast cell cycle distribution. The advantage of this method is the ability to analyze large numbers of cells using multiple cell cycle indicators in a relatively short amount of time.
