人胰岛素溶液可作为添加剂用于Dulbecco′改良eagle′培养基(DMEM)培养上皮细胞系和人子宮內膜细胞系,用于最低必需培养基培养人乳腺癌细胞系,用于培养基199培养正常卵巢细胞系。人胰岛素溶液用于细胞培养的浓度建议为0.5-1 mL/L培养基。人胰岛素溶液可用于小鼠和大鼠的胰岛素耐受试验。它还可用于人胚胎干细胞(hESC)的体外培养和hMSC(人间充质基质细胞)的成脂分化。应用:
胰岛素是由胰岛β-细胞分泌的双链多肽激素。其分子量为~5800 Da。α链和β链是由两个链间二硫键所连接的。α链含有一个链间二硫键。
使用方法
重组人胰岛素溶液常添加至培养基中用于细胞培养,使用培养基稀释到目的浓度即可。也可用无菌水或PBS稀释。1. 根据实验需求,将重组人胰岛素溶液稀释到所需的工作浓度。许多细胞培养基中胰岛素的常用浓度为1-10 μg/mL,主要根据细胞类型来决定。2. 将稀释好的溶液根据目的浓度添加到培养基中。例如,如果你需要在100 mL培养基中添加5 μg/mL的胰岛素,可以加入500 μL的10 μg/mL胰岛素溶液。

Insulin is a two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond.
Application
Insulin solution human has been used as a supplement in Dulbecco′s modified eagle′s medium (DMEM) to culture epithelial cell line and human endometrial cell line, minimum essential medium eagle to culture human breast adenocarcinoma cell line and medium 199 to culture normal ovarian cell line.
Insulin solution human is recommended for use in cell culture applications at 0.5 to 1mL per liter of medium.
Insulin solution human has been used for insulin tolerance test in mice and rats. It has also been used for adipogenic differentiation of human embryonic stem cells (hESCs)-derived outgrowth cultures and hMSCs (human mesenchymal stromal cells).
Usage
Recombinant human insulin solution is often added to the medium for cell culture, and the medium is diluted to the target concentration. It can also be diluted with sterile water or PBS. 1.According to the experimental requirements, the recombinant human insulin solution was diluted to the required working concentration. The common concentration of insulin in many cell cultures is 1-10 μg / mL, which is mainly determined by cell type. 2.Add the diluted solution to the medium according to the target concentration. For example, if you need to add 5 μg / mL insulin to 100 mL medium, 500 μL of 10 μg / mL insulin solution can be added.
