title: Characteristics of 3H-tifluadom binding in guinea-pig brain membranes.
abstract: 3H-Tifluadom labels specifically recognition sites of opioid kappa receptors. Membranes of guinea-pig whole brain bind 3H-tifluadom with two affinities, in contrast to the cerebellum where almost all opioid sites are kappa.
