title: Synthesis and radioreceptor binding activity of turkey beta-endorphin and deacetylated salmon endorphin.
abstract: Des-acetylated salmon endorphin and turkey beta-endorphin have been synthesized by the solid-phase method. Relative opiate activities in a radioreceptor binding assay are: human beta-endorphin, 100; des-acetylated salmon endorphin, 169; turkey beta-endorphin, 94. Thus, non-mammalian endorphins can show high activity in a mammalian assay system.
