Fig. 5. Tethering of LacI-JIL-1 to lacO repeat insertion lines using a late-onset Sgs3-GAL4 driver. The figure shows polytene squash preparations double labeled with LacI antibody (green) and propidium iodide (red or gray). (A) Homozygous preparation for the band insertion line P11.3. (B) Heterozygous preparation for the interband insertion line 4D5. Arrows in A,B point to areas of compacted chromatin that were decondensed where LacI-JIL-1 was targeted.
