4-Methylumbelliferyl Palmitate (Synonyms:4-甲基伞形基棕榈酸酯;4-甲基伞形酮棕榈酸酯;5-氯-3,4-二氢-1H-2-萘酮)
目录号 : KCM12009 CAS No. : 17695-48-6 纯度 : ≥98%
Cholesterol ester storage disease and Wolman disease are recessive autosomal disorders caused by a deficiency in lysosomal acid lipase (LAL), also known as cholesteryl ester hydrolase. 4-Methylumbelliferyl palmitate (4-MUP) is a fluorogenic substrate for lysosomal acid lypase (LAL). 4-MUP is cleaved by LAL to release the fluorescent moiety 4-MU. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases. 4-MUP may also be cleaved by other acid lipases. Recent advances allow the assessment of LAL activity in very small blood volumes using 4-MUP.

生物活性

4-Methylumbelliferyl Palmitate is an excellent fluorophore for measuring acid lipase in human leukocytes. Acidity and solvent have important influence on its fluorescence. 4-Methylumbelliferyl Palmitate exists mainly as neutral molecular form which can be produced strong fluorescence at 445 nm in near neutral aqueous solutions, and exist mainly as anion form which can be produced stronger fluorescence at 445 nm in weak alkaline solutions.

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 ddH2O,混匀澄清。

配置后的溶液总体积:

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。
