| 研究背景 | Interleukin-22 (IL-22) is a member of a group of the IL-10 family, a class of potent mediators of cellular inflammatory responses. IL-22 is produced by activated DC and T cells. IL-22 and IL-10 Receptor chains play a role in cellular targeting and signal transduction. It can initiate and regulate innate immune responses against bacterial pathogens especially in epithelial cells such as respiratory and gut epithelial cells. IL-22 along with IL-17 likely plays a role in the coordinated response of both adaptive and innate immune systems. IL-22 also promotes hepatocyte survival in the liver and epithelial cells in the lung and gut similar to IL-10. Biological activity of IL-22 is initiated by binding to a cell-surface complex consisting of IL-22R1 and IL-10R2 Receptor chains. IL-22 biological activity is further regulated by interactions with a soluble binding Protein, IL-22BP. IL-22BP and an extracellular region of IL-22R1 share sequence similarity. In some cases, the pro-inflammatory versus tissue-protective functions of IL-22 are regulated by Cytokine IL-17A. |

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：
比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL， 一共给药动物10只，您使用的配方为 10% DMSO + 40% PEG300 + 5% Tween 80 + 45% Saline / PBS / ddH2O， 那么您的工作液浓度为2 mg/mL。
母液配置方法：2 mg 药物溶于 100 μL DMSO （ 母液浓度为 20 mg/mL ）, 如您需要配置的浓度超过该产品的溶解度，请先与我们联系。
体内配方的制备方法： 取 100 μL DMSO 母液， 添加 400 μL PEG300 混匀澄清， 再加 50 μL Tween 80, 混匀澄清, 再加 450 μL Saline / PBS / ddH2O 混匀澄清
以上为“体内实验配液计算器”的使用方法举例，并不是具体某个化合物的推荐配制方式，请根据您的实验动物和给药方式选择适当的溶解方案。
方案所需的各类助溶剂如： DMSO， PEG300， PEG400， Tween 80， SBE-β-CD， 玉米油等， 均可在诺渊网站点击购买。
计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL Saline/PBS/ddH2O，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
