Three polyethyleneimine-metal complexes were synthesized and cytochemically tested for demonstration of negatively charged sites. For this purpose rat cerebral cortex synaptosomes were used. It was established that both types of polyethyleneimine-copper complexes labeled the synaptosomal membrane and synaptic vesicles with electron-dense granules, whereas the polyethyleneimine-lead complex marked the anionic sites with amorphous electron-dense material.
合成了三种聚乙烯亚胺-金属络合物，并进行了细胞化学测试以显示带负电荷的位点。为此使用了大鼠大脑皮质突触体。已确定两种类型的聚乙烯亚胺-铜络合物都用电子致密颗粒标记突触体膜和突触小泡，而聚乙烯亚胺-铅络合物用无定形电子致密物质标记阴离子位点。
