Fig. 4. Drosophila Incenp becomes undetectable at stage 13 of embryonic development in incenp^EC3747. Ventral view of stage-13 embryos. (A-A") Wild-type embryos, showing mitotic cells staining positive for (A') Drosophila Incenp and (A") phosphorylated histone H3. (B-B") Homozygous incenp^EC3747 embryos at the same stage show no (B') Drosophila Incenp or (B") phosphorylated histone H3. Insets in A and B show the DNA staining (DAPI). Notice that the embryos have developed normally up to this stage. In the merged figures, DAPI is shown in blue, phosphorylated histone H3 in red, Drosophila Incenp in green.
