Summary
The ratio between large and small carboxy-terminal forms of cholecystokinin in brain extracts from man, pig, dog, rat, chicken, frog and trout was determined by two sequence-specific radioimmunoassays. It was found that the relative amounts of large forms of cholecystokinin; are higher in mammalian brain than in brains of lower species.
