parallel studies with t. marmorata acchor-rich membranes show that in the presence of ca2+ tpo causes a decrease in the apparent equilibrium dissociation constant of the noncompetitive blocker [ 3h ] phencyclidine , enhances , at low concentrations , the binding of [ 3h ] acetylcholine , and also alters the binding kinetics of the fluorescent agonist 6- ( 5-dimethylamino-1-naphthalenesulfonamido ) -n-hexanoic acid beta- ( n-trimethylammonium bromide ) ethyl ester to the acchor .
