Fig. 8. Rig protein shuttles between the nucleus and cytoplasm in larval salivary gland cells. Larval salivary glands dissected from third instar larvae staged 18-24 hours (A-C), 24-30 hours (D-F), or 36-42 hours (G-I) after the molt, or newly formed prepupae (J-L), were fixed and stained to detect Rig protein (red). A mouse anti-histone antibody was used to counterstain nuclei (green).
