Fig. 9. Mis-expression of Dup has distinct effects on amplification of chorion genes. Confocal images of BrdU labeling (red) of amplification foci within mid-stage 10B follicle cell nuclei (Toto-3, blue) 3 hours after expressing different Dup proteins. (A) Wild-type, (B) FL-Dup, (C) C-Dup, (D) Dup 10(A). All images were taken at the same exposure. Scale bar: 10 µm (A-D).
