POF and CHRIZ localization on the polytene fourth chromosome of D. melanogaster. a Phase contrast image of the fourth chromosome. b CHRIZ staining. Antibodies are the same as in Gortchakov et al. (2005). c Merged phase contrast and CHRIZ staining. d POF staining. Antibodies are the same as in Larsson et al. (2001). e Merged phase contrast and POF staining. f Merged CHRIZ and POF staining. g Merged phase contrast, CHRIZ, and POF staining. The arrow indicates the 102B5-6/B7 interband where no POF and CHRIZ binding was observed.
