Recombinant Human Insulin 【Insulin】重組人胰島素 細(xì)胞因子產(chǎn)品描述：

胰島素降低血糖濃度。它增加細(xì)胞滲透性單糖、氨基酸和脂肪酸。戊糖磷酸循環(huán),加速糖酵解和糖原合成在肝臟。
人胰島素重組蛋白是在大腸桿菌中重組表達(dá)的，是由兩條鏈非糖基化多肽鏈組成的二聚體；每條多肽鏈包含有51個(gè)氨基酸，分子量為5807Da。該人胰島素重組蛋白最終由標(biāo)準(zhǔn)的色譜技術(shù)純化出。
來源宿主---大腸桿菌中重組表達(dá)

Recombinant Human Insulin 【Insulin】重組人胰島素 細(xì)胞因子產(chǎn)品使用須知：
溶解：提供的人胰島素(Insulin)產(chǎn)品為過濾滅菌的白色凍干粉末；該凍干粉末是從含1mg/ml人胰島素(Insulin)的溶液（不含添加劑）中凍干產(chǎn)生的。我們建議加無菌的0.005N HCl以配制工作儲存液到1 mg/ml。
保存：人胰島素(Insulin)在室溫可保存3周，或置于-18℃凍存用于長期保存。重新溶解后可以在4℃冷藏保存至少2-7天；如果想延長保存時(shí)間，建議分裝（加載體蛋白如0.1% HSA或 BSA）后置于-18℃凍存。請避免反復(fù)凍融。

Introduction 

Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.

Description 

Insulin Human Recombinant produced in E.Coli is a two chain, non-glycosylated polypeptide chain containing 51 amino acids and having a molecular mass of 5807 Dalton. Insulin is purified by proprietary chromatographic techniques.

Source 

Escherichia Coli.

Physical Appearance  （外觀）

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation  

The protein was lyophilized from a concentrated (1mg/ml) solution with no additives.

Solubility    （溶解性）

It is recommended to reconstitute the lyophilized Insulin in sterile 0.005N HCl not more than 1 mg/ml.

Stability       （穩(wěn)定性）

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

Purity        （純化）

Greater than 98.0% as determined by

(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Biological Activity   （生物活性）

The Biological Activity was determined to be 28 units/mg.
