abstract：:Acid-urea extract of rat brain was examined by glucagon-like peptide-1 (GLP-1) specific radioimmunoassay. A single peak was observed which co-eluted with GLP-1(7-36)amide on gel filtration and anion exchange chromatography. In contrast, GLP-1(1-37) was not detected under our experimental conditions. The fact that GLP-...
