产品信息

描述 The R-Spondin (Rspo) proteins belong to the Rspo family of Wnt modulators. Currently, the family consists of four structurally-related, secreted ligands (Rspo 1-4), all containing furin-like and thrombospondin structural domains. The Rspo proteins can interact with the Frizzled/LRP6 receptor complex in a manner that causes the stabilization, and resulting accumulation, of the intracellular signaling protein, beta-catenin. This activity effectively activates and increases the subsequent nuclear signaling of beta-catenin. R-Spondin can also bind to the previously discovered G-protein coupled receptors, LGR-4 and LGR-5. Rspo/beta-catenin signaling can act as an inducer of the transformed phenotype, and can also regulate the proliferation and differentiation of certain stem cell populations.
研究背景 Recombinant Human R-Spondin-2 is a 24.4 kDa protein consisting of 212 amino acid residues. Due to glycosylation, R-Spondin-2 migrates at an apparent molecular weight of approximately 30.0 kDa by SDS PAGE analysis under reducing conditions.This product is shipped at ambient temperature.

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。
