Cholecystokinin (CCK) binding to its receptors on a muscularis membrane fraction of bovine gallbladder was characterized using a biologically active CCK-33-[125I]Bolton-Hunter conjugate. Receptor binding was localized to the muscularis layer of the gallbladder; no binding was seen on either mucosal or serosal membranes. At 24 degrees C and pH 6.5, binding was maximal after 60-90 min of incubation, remained at a plateau for at least 240 min, and was reversed by the addition of unlabeled CCK-8… CONTINUE READING
