Abstract excerpt
Cholecystokinins from brain and small intestine of the bullfrog (Rana catesbeiana) and red-eared slider turtle (Pseudomys scripta) were isolated. The purifications were monitored by an antiserum specific for the common C-terminus of mammalian cholecystokinin and gastrin. The peptide structures we...
