GLP-1(7-37) acetate is an intestinal insulinotropic hormone that augments glucose induced insulin secretion[1].
GLP-1(7-37) (0.5, 5 or 50 pmol/min/kg) infused during the second hour of a 2-hour 11-mM hyperglycemic clamp produces a dose-related enhancement of the glucose-stimulated increase in plasma insulin concentration and an increased rate of glucose infusion in rats[2].Infusion of GLP-1(7-37) (5 pmol/min/kg) from 1 hour through 7 hours produces a sustained increase in plasma insulin concentration relative to levels in rats infused with vehicle in rats with maintained glucose concentration at 11 mM[2]. Animal Model: Male Sprague-Dawley rats weighing 300 to 350 g with glucose IV at a variablerate for 7 hours to maintain plasma glucose concentration at 11 mM[2].
