membrane preparations from guinea-pig brain were used to study the effects of temperature on the interaction of [ 3h ] [ d-ala2-mephe-gly-ol5 ] ( dago ) , a selective mu agonist , [ 3h ] [ d-ala2 , d-leu5 ] enkephalin ( dadle ) , a nearly selective delta agonist and ( +/- ) [ 3h ] ethylketazocine ( ekc ) , a selective kappa agonist when binding was measured in the presence of an excess of dago and dadle .
