Description | 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[1][2]. |
