title: Muscarinic cholinergic receptors in murine lymphocytes: demonstration by direct binding.
abstract: Using [3H]quinuclidinyl benzilate as a specific cholinergic muscarinic ligand, it has been demonstrated that lymphocytes have muscarinic binding sites. There are approximately 200 sites per cell and the dissociation constant for quinuclidinyl benzilate is approximately 1 X 10(-9) M. Quinuclidinyl benzilate receptor binding is blocked by atropine and oxotremorine.
