in this paper we examine the effect of beta-fna on the binding of the prototypic delta agonists , leu-enkephalin and d-ala2-d-leu5-enkephalin , its metabolically stable analogue , and show that treatment of membranes with beta-fna does lead to alterations in the in vitro properties of delta receptors .
