[Radioimmunoassay of motilin (author's transl)]

A specific radioimmunoassay for motilin is described and a few technical details concerning antibody production and tracer iodination are discussed. Though a variety of biological actions of motilin have been reported, its role in normal human physiology remains to be established. So far, the motilin radioimmunoassay brought no major break through to elucidate the physiology, disregard pathophysiology, of motilin.
