Movie 3

Live-imaging of RNAP2 Ser2ph and H3K27ac in zebrafish developing embryo.
The embryo injected with Fabs specific to RNAP2 Ser2ph (Alexa488), H3K27ac (Cy3), and H3K9ac (Cy5) was imaged using a confocal microscope (FV1000). Twenty five z-sections with 4 μm intervals were collected, and single confocal sections for RNAP2 Ser2ph and H3K27ac were selected to make a movie. Elapsed time is indicated as min:sec.
