DiFMUP is a fluorogenic substrate, and has been widely used for the continuous detection of phosphatase activities. DiFMUP is hydrolysis by a phosphatase results in the release of Xuorescent DIFMU, which can be easily followed in continuous mode by a Xuorescence reader.

体外研究(In Vitro)
DIFMUP (100 μM; 0-4 min) is hydrolyzed by protein tyrosine phosphatase 1B (PTP1B) in a time-dependent manner and the initial rate of the reaction velocity is increased with the enzyme concentration (30-600 ng/mL). has not independently confirmed the accuracy of these methods. They are for reference only.
