title: Anomalous binding of [3H]N-methyl-quinuclidinyl benzilate methyl chloride to human lymphocyte muscarinic receptors.
abstract: Using the muscarinic cholinergic ligand [3H]N-methyl quinuclidinyl benzilate methyl chloride ([3H]NM-QNB), we demonstrated that intact, viable human lymphocytes possess specific muscarinic binding sites. Equilibrium binding studies show that muscarinic acetylcholine receptor are divided into two subtype; high affinity (Ms) and low affinity types (Mw) for the ligand.
