Abstract
The electron cytochemical demonstration of adenylate cyclase activity was carried out in rat cortical synaptosomes. Reaction product was found in 60-70% of the synaptosomes in three predominant localization: (i) on the postsynaptic density; (ii) on the outer aspect of the synaptosomal membrane; (iii) inside the synaptosome. Results suggest that in addition to postsynaptic localization adenylate cyclase activity is cytochemically demonstrable also at presynaptic sites.
摘要
在大鼠皮质突触体中进行了腺苷酸环化酶活性的电子细胞化学证明。在60%-70%的突触体中发现反应产物，有三个主要定位：（i）在突触后致密部；（ii）在突触体膜的外表面；（iii）在突触体内。结果表明，除了突触后定位外，腺苷酸环化酶活性在突触前位点也可通过细胞化学方法证明。
