Description_x000D_ General description_x000D_ Glucagon is a hormone peptide produced in Langerhans islets α-cells in the pancreas. The active form of glucagon is derived from the cleavage of preproglucagon (GCG). Additional cleavage peptides are oxyntomodulin and glucagon-like peptide-1 (GLP1)._x000D_ Immunogen_x000D_ Polymerized porcine glucagon_x000D_ Application_x000D_ Monoclonal Anti-Glucagon antibody produced in mouse has been used in immunofluorescence staining. The product may be used in several immunochemical techniques including immunohistochemistry and radioimmunoassay (RIA)._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ ExtrAvidin is a registered trademark of Sigma-Aldrich Co. LLC_x000D_ Biochem/physiol Actions_x000D_ The biological activities of pancreatic glucagon include glycogenolysis, lipolysis, gluconeogenesis and ketogenesis. Glucagon has an antagonistic effect in the maintenance of normoglycemia to those of insulin and is suppressed by GLP1. Thus up-regulation of glucagon is leading to increased blood glucose levels. Glucagon-specific antibodies would prove useful as a Langerhans islets α cell, glucagonomas and tumor markers applying immunohistochemical techniques, and as an analytical tool in quantification of the hormone.
