4-Nitrophenyl-N-acetyl-β-D-glucosaminide is a chromogenic substrate for N-acetyl-β-glucosaminidase.1,2 Hydrolysis of 4-nitrophenyl-N-acetyl-β-D-glucosaminide by N-acetyl-β-glucosaminidase releases 4-nitrophenol, which can be quantified by colorimetric detection at 405 nm as a measure of N-acetyl-β-glucosaminidase activity. It has been used to quantify the activity of N-acetyl-β-D-glucosaminidase in human serum and urine in parenterally fed patients.3

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,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。
