背景資料

Glucagon is an important hormone involved in carbohydrate metabolism. The hormone is synthesized and secreted from alpha cells （?-cells） of the islets of Langerhans， which are located in the endocrine portion of the pancreas. Glucagon is released when the glucose level in the blood is low （hypoglycemia）， causing the liver to convert stored glycogen into glucose and release it into the bloodstream. The action of glucagon is thus opposite to that of insulin， which instructs the body’s cells to take in glucose from the blood in times of satiation.
Glucagon is beneficial for the culture of some cell types. It has been used in some biochemical regulation studies of glycogenolysis in hepatocytes. It has been also been found to induce DNA replication in primary cultures of adult rat hepatocytes when used in combinations with EGF and Insulin. Glucagon increases the blood glucose concentration by promoting rapid breakdown of liver glycogen， and also acts to relax smooth muscle such as the gastrointestinal tract.

來源宿主

大腸桿菌中重組表達(dá)

溶解建議

提供的重組人胰高血糖素產(chǎn)品為白色無菌凍干粉末.推薦使用無菌的18MΩ的超純水來溶解，濃度不低于100ug/ml，便于后續(xù)稀釋.

保存建議

Lyophilized Glucagon although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Glucagon 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.

其他

ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗(yàn)，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長因子、瘦素、干細(xì)胞因子、催乳素、表皮生長因子、胰島素樣生長因子、神經(jīng)生長因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。  生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級(jí)蛋白，價(jià)格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒有添加保護(hù)劑或鹽，這就對(duì)工藝提出了更高的要求。同時(shí)，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運(yùn)輸和保存。
