重组醋酸艾塞那肽

背景资料:
Exedin-4 Recombinant is a glucagon like peptide-1 receptor agonist. The native hormone is produced in the gut of Gila monster Heloderma suspectrum （a type of reptile found in the desert） that stimulates insulin production without causing threateningly low blood sugar， which can occur after using insulin and some anti-diabetes products. Recently， researchers used extracted saliva from gila monsters to create an unprecedented breakthrough in Diabetes Type 2 treatment. Unlike other products taken for type 2 diabetes， Exedin-4 has not bExendin-4 Recombinant is a novel 39-amino acids peptide having a molecular mass of 4186.7 Dalton， which shares 53%， sequence homology with GLP-17-36 amide and interacts with the same membrane receptor.The Exendin-4 is purified by proprietary chromatographic techniques.n linked with weight gain and actually resulted in weight loss， according to the researchers. Exedin-4 enhances glucose-dependant insulin secretion， suppresses inappropriately elevated glucagon secretion and slows gastric emptying in vivo. It also promotes B-cell proliferation and neogenesis in vitro and in animal models. Exedin-4 stimulates an increase in acinar cAMP， without stimulating the release of amylase.

溶解建议:
提供的重组醋酸艾塞那肽产品为白色无菌冻干粉末，冻干之前是在4%甘露醇糖的20mM PBS缓冲液中透析过.推荐使用无菌的18MΩ的超纯水来溶解，浓度不低于100ug/ml，便于后续稀释.

保存建议：
Lyophilized Exendin Recombinant although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Exendin-4 should be stored at 4℃ between 2-7 days and for future use below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.Please prevent freeze-thaw cycles.
