Other Notes

Originally isolated from Heloderma suspectum (Gila monster lizard) venom.

Lyophilized from 0.1% TFA in H2O

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Application

Exendin-4 has been used for the treatment of ob/ob mouse model to determine the glucose and insulin concentrations and homeostasis model of assessment (HOMA), and for the determination of nuclear factor-κΒ (NF-κB) p65 level in macrophages treated with exendin-4.

Biochem/physiol Actions

Exendin-4 mimics the activity of mammalian incretin hormone glucagon-like peptide 1 (GLP-1), and thus, functions in the control of glucose. This includes the secretion of insulin in a glucose dependent manner, negative regulation of high glucagon secretion, and increased duration of stomach emptying. In type 2 diabetes patients, this peptide can be administered subcutaneously for glycemic control, when metformin is unable to produce adequate results. It promotes the neogeneration and proliferation of β-cells, and thus aids in the regeneration of pancreas. It acts as a ligand to exendin receptor, and leads to an elevation of acinar cell cAMP levels.

General description

Exendin-4 is an incretin mimetic peptide, which is composed of 39 amino acids. It is an analog of glucagon-like peptide 1 (GLP-1), and an insulinotropic agent, with a long half-life. It was originally isolated from the venom of Gila monster lizard called Heloderma suspectum.
