Research Abstract

In order to visualize secretory granules in rat parotid acinar cells, we incubated the cells with a fluorescent dye for 3 hours after exocytosis. Intracellular localization of the dye into secretory granules was confirmed by morphological, biochemical and functional study. Moreover immature secretory granules including the dye matured to large after 2 days cell culture. These results expect that examination of mechanisms of granule maturation in rat parotid granules.
