Fig. 5. Cyclin levels in the CNS of third instar larvae lacking the baf gene. Cyclins A, B and E were detected with specific antibodies in baf¹/baf¹ or baf¹/+ CNS tissues. In baf¹/baf¹ tissues, immunofluorescence images are presented in the upper panels, and the same fields labeled with PI, to identify nuclei, are shown in the lower panels. In the case of baf¹/+ tissues, only immunofluorescence images are shown. Scale bars: baf¹/baf¹ panels, 50 µm; baf¹/+ panels, 100 µm. All images were recorded with a confocal microscope.
