B. PARKER A1 C. GOLDFINE YR 1973 UL http://jpet.aspetjournals.org/content/185/3/649.abstract AB Appropriate estimation of drug-receptor dissociation constants with pharmacological techniques depends upon the stoichiometry of the reaction involved. The data presented in this paper suggest that both stimulant drugs and competitive antagonists interact on a one-to-one basis with the nicotinic receptor of the guinea-pig lumbrical muscle. © 1973 by The Williams & Wilkins Co.
