Description:

Exendin-4 mimics the incretin hormone glucagon-like peptide 1 (GLP-1) and shares 53% sequence homology with GLP-17-36 amide. Interacts with the same membrane receptor, GLP1R, and induces hypotension that is mediated by relaxation of cardiac smooth muscle. The native hormone is found in the venom of the Gila monster (Heloderma suspectrum). Exendin-4 enhances glucose-dependent insulin secretion, suppresses inappropriately elevated glucagon secretion, and slows gastric emptying in vivo. It also promotes β-cell proliferation and neogenesis in vitro and in animal models.

Reconstitution:

Centrifuge vial prior to opening. Add sterile distilled water or aqueous buffer to a concentration of 0.1-1.0 mg/ml. Further dilutions should be made in appropriate buffered solutions.

Storage/Stability:

Upon receipt store at -20°C to -80°C for up to 1 year. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -80°C. Avoid repeated freeze/thaw cycles.
