Notes:
The isolation of synaptic vesicles from mouse brain by a modification of previously reported methodology is described. Homogeneity of the preparations was ascertained by electron microscopy. Vesicles thus isolated contained cyclic AMP (365 ± 44 pmol/mg of protein; mean ± S.E.M.) and adenosine 3′,5′-monophosphate phosphodiesterase activity (500 pmol/mg of protein per 30 min). The number of vesicles in three of the vesicle preparations was determined by a visual count of grid fields under the electron microscope. The content of cyclic AMP in the vesicles was calculated at 5000-7500 molecules/vesiclc. The presence of cyclic AMP in the synaptic vesicles from presynaptic nerve endings would support a role for this nucleotide in nerve transmission.
