Fig. 4. HOPS localization in liver following cAMP induction. (Left colum) Localization of HOPS (anti-HOPS) in normal liver and at 15, 30, 60, 90 and 120 minutes following intraperitoneal injection of cAMP. (Middle column) DAPI staining of the same slides at different times following cAMP injection. (Right column) Merged images of anti-HOPS and DAPI. Scale bars: 20 µm.
