Vesicle fusion enhanced by Ca2+. Fluorescence intensity of bulk-vesicle fusion was measured by lipid mixing. Ca2+ treatment in the presence of Syt1 increases fluorescence by vesicle–vesicle interactions, indicating that low concentration of Ca2+ stimulates synaptic exocytosis. The 100 μM Ca2+ condition was chosen for experiments.
