Fluorescence microscopy of H2A.Z-1 and H2A.Z-2 variants in mouse embryonic fibroblasts. A mouse embryonic fibroblast nucleus is shown following transfection with H2A.Z-2-YFP and H2A.Z-1-cyan fluorescent protein (CFP) and imaged live. The top left panel shows cells stained with DNA binding dye Hoechst 33342. The top right panel shows the distribution of H2A.Z-2-yellow fluorescent protein (YFP). The bottom left panel shows the distribution of H2A.Z-1-CFP while the composite image shows the Hoechst staining (green) relative to the distribution of H2A.Z-2-YFP. Sites that are enriched in H2A.Z-2 are orange and are predominantly euchromatin. The chromocenters appear yellow, indicating the presence of both DNA and H2A.Z-2-YFP.
