1 The binding properties of the muscarinic receptors in the ciliary muscle of cynomolgus monkeys have been evaluated. 2 The concentration of receptor binding sites is the highest yet reported. As found in many species and tissues, there are subclasses of agonist binding sites. Agonist binding is not affected by the non‐hydrolysable guanosine triphosphate (GTP) analogue, GppNHp, suggesting that these receptors are not linked to adenylate cyclase. 3 Ciliary muscles made subsensitive by treatment with muscarinic agonists have a decreased receptor concentration but no other changes in the binding properties of the receptors could be detected.
