Figure 7. Chromatin environment of Corto.

Co-immunostainings of salivary gland polytene chromosomes from w¹¹¹⁸ larvae using anti-Corto antibodies (green) and anti-H3K27me3 (A), anti-H3K4me3 (B), anti-RNAPolIIS5p (C) or anti-RNAPolIIS2p (D) antibodies (red). The two arrows in A point to X chromosome tips from two nuclei. Some co-localizations between Corto and H3K4me3 or RNAPolIIS2p are shown with yellow arrows on the merged pictures. (E) Close-up showing co-localizations of Corto and RNAPolIIS5p. (F) Close-up showing rare co-localizations of Corto and RNAPolIIS2p.
