Biosynthesis of peptides in vitro in male rat hypothalamic fragments wasinvestigated by incubating the tissue with 14C-labelled leucine, proline and glycine. Depending on the amino acid used, 4 or 6 labelled peptides were extracted from the tissue fragments with organic solvent mixture. The incorporation of the label into peptides was time dependent. LH-RH and oxytocin thus synthesized were identified by thin layer chromatography and high voltage electrophoresis using cold LH-RH and oxytocin as standards.
