Background: Gastric inhibitory polypeptide (GIP), also known as the glucose-dependent insulinotropic peptide is a member of the secretin family of hormones. GIP, together with glucagon-like peptide-1 (GLP-1), belongs to the group of metabolic hormones called incretins that stimulate a decrease in blood glucose levels. GIP is derived from a 153-amino acid pro-protein encoded by the GIP gene and circulates as a biologically active 42-amino acid peptide. Engagement of Gastric inhibitory polypeptide receptors (GIPR) by GIP on pancreatic beta cells activates adenylate cyclase to regulate insulin compensation in the presence of high circulating glucose.
Bio Acitivity: Not validated for activity
Sequence: Glu 22-Arg 153
Purity: > 95% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
Endotoxin: < 10 EU/mg of the protein as determined by the LAL method.
