摘要：

The binding of the .alpha.2-adrenoceptor ligands [3H]yohimbine and [3H]idazoxan to rabbit kidney and forebrain membranes was compared. The maximum number of [3H]yohibine binding sites was higher than the number of [3H]idazoxan binding sites in forebrain and lower in kidney. Large differences were observed in the ability of noradrenaline, adrenaline, idazoxan, rauwolscine, yohimbine and WY 26392 to displace [3H]yohimbine and [3H]idazoxan from their binding sites. These data suggest that [3H]idazoxan and [3H]yohimbine bind to different sites on rabbit tissue membranes.
