Immunoreactive somatostatin and luteinizing hormone releasing hormone in median eminence synaptosomes of the rat: detection by immunohistochemistry and quantification by radioimmunoassay.
Somatostatin and LHRH were detected by radioimmunoassay in the synaptosome fraction obtained by homogenization and differential centrifugation of the rat median eminence. Both somatostatin and LHRH were demonstrated by electron microscopic immunocytochemistry in secretory granules within synaptosomes.
