4-Methylumbelliferyl-2-acetamido-2-deoxy-β-D-glucopyranoside is a fluorogenic substrate for β-hexosaminidases. Upon enzymatic cleavage by β-hexosaminidases, 4-methylumbelliferone (4-μU) is released and its fluorescence can be used to quantify β-hexosaminidase activity. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high pH (7.12-10.3), respectively, and an emission maximum ranging from 445 to 455 nm, increasing as pH decreases. 4-Methylumbelliferyl-2-acetamido-2-deoxy-β-D-glucopyranoside has been used to quantify β-hexosaminidase activity in serum or leukocytes from patients with GM2 gangliosidoses such as Tay-Sachs disease, which is characterized by defects in the α subunit of β-hexosaminidase.

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：
TargetMol | Animal experiments 比如您的给药剂量是10 mg/kg，每只动物体重20g，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%Saline/PBS/ddH2O， 那么您的工作液浓度为2mg/mL。
母液配置方法: 2 mg 药物溶于 50 μLDMSOTargetMol | 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 50μLDMSOTargetMol | reagent 母液，添加 300 μLPEG300TargetMol | reagent 混匀澄清，再加 50μLTween80, 混匀澄清，再加 600μLSaline/PBS/ddH2OTargetMol | 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。
