title: Biochemical studies on muscarinic receptors in the salamander olfactory epithelium.
abstract: Muscarinic cholinergic receptors in the olfactory epithelium of the salamander, Ambystoma tigrinum, were studied via binding of 3-[3H]quinuclidinyl benzilate. The receptors are present on the olfactory receptor cells in the epithelium to an amount of 0.08 pmol/mg homogenate protein. Both choline acetyltransferase and acetylcholine esterase are present in the salamander olfactory epithelium.
