Abstract [3 H] Rauwolscine, a specific and potent α 2-antagonist radioligand, was used to characterize α 2-receptor binding in bovine cerebral cortex [3 H] Rauwolscine binding was reversible, stereospecific, and saturable. Association, dissociation, and saturation studies revealed one site interactions (k− 1 k+ 1= 1.2 nM, K D= 2.5 nM, B max= 160 fmol mg protein) and competition studies indicated that [3 H] rauwolscine labeled the α 2-receptor. Agonists inhibited [3 H] rauwolscine binding in a shallow, GTP-sensitive manner. These results suggest that [3 H] rauwolscine specifically labels both the high and low affinity states of the α 2-receptor in brain membranes.
