title: Two different and compatible intraneuronal labels for ultrastructural study of synaptically related cells.
abstract: To examine the structural interactions between synaptically connected neurons in Aplysia, we have developed a method for simultaneously labeling two identified cell with different and compatible intraneuronal marking agents (horseradish peroxidase and [3H]N-acetyl-D-galactosamine) visible in both the light and electron microscopes. Combining these two agents within a single cell yields a third label.
