4-Methylumbelliferyl sulfate (potassium)
4-Methylumbelliferyl sulfate (potassium), a fluorescent substrate, is commonly used to detect sulfatase activity in biochemical and biomedical research. It consists of a sulfate group attached to a fluorescent molecule, which can be cleaved by sulfatase enzymes. Upon cleavage, 4-Methylumbelliferyl sulfate releases a highly fluorescent product that can be detected using fluorescence microscopy or spectroscopy. The use of 4-Methylumbelliferyl sulfate as a substrate for sulfatase enzymes allows accurate detection and quantification of these enzymes in a variety of biological samples.
