The objectives of this study were to develop a sensitive, specific, and reliable radioimmunoassay for plasma cholecystokinin and to use the cholecystokinin radioimmunoassay (CCK RIA) to determine the role of CCK in stimulating exocrine pancreatic secretion. Three rabbits were immunized with synthetic sulfated CCK-10 conjugated to keyholed limpet hemocyanin. Using /sup 125/I-CCK-39 (iodo-gen) as tracer, it was found that antiserum R016 (titer = 1:256,000) recognized short and long forms of CCK and had negligible cross-reactivity with gastrin and other peptides. Plasma CCK levels and pancreatic secretion in fasted dogs (N = 6) were measured in response to a meat meal, intestinal perfusion with saline, graded amounts of sodium oleate (+/-atropine), a mixture of tryptophan/phenylalanine (Trp/Phe), or HCl, and i.v. infusion of graded doses of CCK-8 or CCK-39.
