| 研究背景 | Interleukin-15 (IL-15) is a 14-15 kDa glycoprotein with immune regulatory functions in many diverse cell types. IL-15 can be constitutively expressed in a variety of cell types stored as intracellular protein in the cytoplasm as well as transport to the cell surface, while only secreted from some cell types including monocytes, dendritic cells, epithelial cells, bone marrow stromal cells, and fibroblasts. As a pleiotropic cytokine, IL-15 mediates the crosstalk between innate immunity and adaptive immunity whose principal role is to kill virally infected cells. IL-15 plays a crucial role in the development, differentiation, and survival of NK cells. In monocytes, IL-15 induces the production of IL-8 and monocyte chemotactic protein 1 (MCP-1), which recruits neutrophils and monocytes to sites of infection. IL-15 can also act as a chemo-attractant in T lymphocytes and regulate the differentiation of T lymphocytes. |

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。
