title: Three-color intranuclear staining for measuring mitosis and apoptosis in cells transfected with a GFP-tagged histone.
abstract: Green fluorescent protein (GFP) has become a powerful tool for monitoring the expression of transfected genes by flow cytometry including GFP-tagged histones for tracking chromatin and elucidating histone function. We describe here a method for simultaneous detection of three nucleus-localized signals: a GFP-tagged histone, DNA content and detection of phosphorylated histone H3, which labels mitotic cells. We also demonstrate another application of this method for simultaneous detection of a GFP-tagged histone, DNA content, and cleaved caspase-3.
