title: Motilin-like-immunoreactivity in intestine and brain of dog.
abstract: Motilin-like-immunoreactivity was detected in various regions of canine intestinal tract and brain. Its content in the brain was much smaller than in the gut. Its regional distribution was not uniform in both organs. On gel chromatography (G-50 SF), intestinal extracts revealed a main molecular form of motilin-like-immunoreactivity corresponding to motilin 1-22, while, in the brain, it eluted predominantly with the void volume. Further characterization of this later substance does not suggest it is strongly related to motilin. Putative motilin precursors of 14 kd and 6 kd are detectable in small concentration in intestinal mucosa.
