title: Met-enkephalin-Arg6-Gly7-Leu8 in large-cored vesicles of splanchnic nerve terminals innervating guinea pig adrenal chromaffin cells.
abstract: Met-enkephalin-Arg6-Gly7-Leu8 (Met-Enk-Arg-Gly-Leu)-like immunoreactivity in the guinea pig adrenal medulla was investigated by the peroxidase-antiperoxidase method for light microscopy and by the protein A-gold method for electron microscopy. Because of a distinct Met-Enk-Arg-Gly-Leu-like immunoreactivity in the splanchnic nerve terminals innervating the chromaffin cell, their distribution and structure were clearly demonstrated. With electron microscopy, specific colloidal gold particles representing Met-Enk-Arg-Gly-Leu were localized in large-cored vesicles.
