|October 1, 1979
Abstract:
A technique for the localization of catecholamines and enkephalin in the same tissue section is described. Sections from rat brains prepared according to the Falck-Hillarp technique were examined by dark field fluorescence microscopy and then processed for immunocytochemistry for leucine-enkephalin (leu-enk) using the unlabeled antibody technique. In the medial hypothalamus the distribution of the catecholamines and enkephalin is complementary, while in the lateral hypothalamus the patterns are similar but not identical. Enkephalin terminals are also observed in and around the locus coeruleus, while enkephalin cell bodies are adjacent to the nucleus.
