摘要：

We have developed a secretion assay composed of semi-intact synaptosomes from which transmitter release is optimally evoked by micromolar Ca2+ in the presence of cytosol. Transmitter release from this preparation reconstitutes known characteristics of regulated exocytosis and is accompanied by a marked decrease in synaptic vesicles. The assay is useful in characterizing the components known to be involved in transmitter release, and should also facilitate the identification of additional factors that are important for this process.
