    Product Description

    [Des-His1,Glu9]-Glucagon (1-29) amide is a peptide glucagon receptor antagonist (pA2 = 7.25 for glucagon binding to isolated rat liver membranes).1 It binds to glucagon receptors in a magnesium- and GTP-independent manner to stimulate breakdown of inositol phospholipids by phospholipase C, but has no effect on adenylate cyclase activity, in hepatocytes.1,2 In vivo, [Des-His1,Glu9]-glucagon (1-29) amide prevents glucagon-induced hyperglycemia in rabbits and decreases blood glucose in rats with diabetes induced by streptozotocin (Item No. 13104).1

    WARNING This product is not for human or veterinary use.
