产品信息

描述 IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and also by mast cells and NK cells. Targeted deletion of IL-13 in mice resulted in impaired Th2 cell development and indicated an important role for IL-13 in the expulsion of gastrointestinal parasites. IL-13 exerts anti-inflammatory effects on monocytes and macrophages and it inhibits the expression of inflammatory cytokines such as IL-1beta, TNF-alpha, IL-6 and IL-8. IL-13 has also been shown to enhance B cell proliferation and to induce isotype switching, resulting in increased production of IgE. Blocking of IL-13 activity inhibits the pathophysiology of asthma. Human and murine IL-13 are cross-species reactive. A variant of IL-13 shows enhanced functional activity compared with the wild type IL-13.
研究背景 PeproTech's genetic variant, termed Recombinant Human IL-13 Variant, is a mature 115 amino acid protein with a substitution of Q for R at position 113. The calculated molecular weight of Recombinant Human IL-13 Variant is 12.6 kDa.This product is shipped at ambient temperature.

生物活性 This IL-13 analog shows a two fold increase, relative to wild type IL-13, in bioactivity as measured by the in vitro dose dependent activation of STAT6 and IL-13 dependent gene induction in transfected A201.1 cells. This analog has also been shown to exhibit increased in vivo activity compared to wild type IL-13, as measured by the induction of airway hyper-responsiveness.

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。

第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶于水的药物;不同批次药物配方比例不同,请联系客服为您提供正确的澄清溶液配方)

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。
