Bis(4-methylumbelliferyl)phosphate (Highly Pure) – Research Use Only

Bis(4-methylumbelliferyl)phosphate (Highly Pure) is a biotechnology-grade fluorogenic phosphodiester substrate supplied as a 100 mg powder for research applications involving enzyme activity assays, phosphodiesterase studies, sphingomyelinase analysis, and biochemical screening workflows. This substrate is widely used in fluorescence-based methods where enzymatic cleavage releases 4-methylumbelliferone-derived fluorescent signal, enabling sensitive detection of target enzyme activity. It is especially useful in workflows related to lysosomal enzyme research, lipid metabolism studies, diagnostic assay development, and mechanistic biochemical analysis.

Scientific Overview

Bis(4-methylumbelliferyl)phosphate is a well-established fluorogenic substrate used in biochemical workflows to evaluate enzyme activity through release of a fluorescent product. Because 4-methylumbelliferone-based substrates are widely used in sensitive enzymatic detection systems, this compound is especially valuable in assays requiring high signal sensitivity and quantitative fluorescence readout.

In laboratory settings, this reagent is commonly associated with studies involving phosphodiesterase activity, sphingomyelinase characterization, lysosomal enzyme analysis, and disease-related enzyme function screening. It is particularly relevant to researchers working in lipid metabolism, neurochemistry, inherited metabolic disease research, and assay development involving phospholipid-processing enzymes.
