Characterization of [3H]Ro5-4864 binding to "peripheral" benzodiazepine receptors in guinea pig alveolar type II cells.
The binding of [3H]Ro5-4864 to peripheral benzodiazepine receptors has been demonstrated in a highly purified preparation of alveolar type II cells. [3H]Ro5-4864 binding to guinea pig alveolar type II cells indicated one population of binding sites with high affinity (KD = 5.7 nM) and saturability (Bmax = 4582 fmol/mg membrane protein).
