产品介绍

生物活性

产品描述	4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside for detecting α-galactosidase activity. The amount of released pNP is significantly increased when PNP-alpha-D-Gal is used as substrates.
体外活性	Using 4-nitrophenol (pNP)-glycopyranosides as pseudosubstrates, the amount of liberated pNP from the 4-Nitrophenyl α-D-galactopyranoside is significantly higher than that from the other pNP-glycopyranosides at pH 4.0 while no activity was detected at pH 7.0. The digestion assays using pNP glycopyranosides as artificial substrates exhibit that yielding liberated galactose residues from 4-Nitrophenyl α-D-galactopyranoside mainly at pH 4.0, i.e. the pH level where yield threshold is decreased at most.

体内实验配液计算器

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 ， TargetMol | Animal experiments

一共给药动物 10 只 ，您使用的配方为 5% TargetMol | reagent

DMSO+ 30%PEG300+ 5%Tween 80 + 60% 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 50 μLDMSO TargetMol | reagent

（母液浓度为 40 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 50μLDMSO TargetMol | reagent

母液，添加 300 μLPEG300 TargetMol | reagent

混匀澄清，再加 50μLTween 80, 混匀澄清，再加 600μLddH2O TargetMol | reagent

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。
