Electron-microscopic localization of enkephalin-like imnmunoreactivity in axon terminals of human sympathetic ganglia.
The peroxidase-antiperoxidase method was applied to demonstrate enkephalin-like immunoreactivity in the human sympathetic ganglia. A network of immunoreactive fibres was found in light microscopy between the nonreactive neurons. Electron microscopy showed immunostaining to be restricted to axonal profiles containing both large and small vesicles. The strongest reaction was associated with large vesicles.
