Fig. 7. Embryonic expression and subnuclear localization of H1.X. (A,B) show
H1.X::GFP fluorescence detection in a few cells in the periphery of a >
100-cell stage embryos. In (A), a fixed specimen shows a shallow fluorescence
of the nucleoplasm and bright fluorescence of the nucleoli, whereas in (B), a
live observation shows a shallow fluorescence in the cytoplasm and a bright
fluorescence of the nucleoplasm. The brightest spots in the nucleoplasm
correspond to the nucleoli. Bars, 20 µm.
