重组人磷酸化酪氨酸激酶

产品英文名称：
Exenatide

英文简称:
Exenatide

中文名称:
醋酸艾塞那肽

背景资料:
Exenatide Derived from the saliva of the gila monster， is a 39 amino acid peptide that mimics the GLP-1 incretin， an insulin secretagogue with glucoregulatory eects. Typical responses to exenatide include improvements in the initial rapid release of endogenous insulin， suppression of glucagon release by the pancreas， regulation of gastric empyting， and reduced appetite - all of which function to lower blood glucose. Exenatide is self-regulating in that it lowers blood sugar when levels are elevated but does not continue to lower blood sugar when levels return to normal， unlike with sulfonylureas or insulins.

产品描述:
Exenatide is a single， non-glycosylated， peptide containing 39 amino acids and having a molecular mass of 4186.6 Dalton. Exenatide has the empirical formula C184H282N50O60S.

序列:
H-His-Gly-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Leu-Ser-Lys-Gln-Met-Glu-Glu-Glu-Ala-Val-Arg-Leu-Phe-Ile-Glu-Trp-Leu-Lys-Asn-Gly-Gly-Pro-Ser-Ser-Gly-Ala-Pro-Pro-Pro-Ser-NH2.

溶解建议:
提供的醋酸艾塞那肽产品为白色无菌冻干粉末，冻干粉里不含有其它添加剂.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 Exenatide although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Exenatide 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.
