4-Methylumbelliferyl 2-acetamido-2-deoxy-4-O-b-D-galactopyranosyl-b-D-glucopyranoside Galactopyranosyl-b-1,4-N-acetyl-D-glucosamine; Acetamido-2-deoxy-D-lactose; 4-MU LacNAc 4-Methylumbelliferyl 2-acetamido-2-deoxy-4-O-b-D-galactopyranosyl-b-D-glucopyranoside is a chemiluminescent substrate that is used in diagnostic tests. This compound has been approved by the FDA and EPA for use in food testing, as well as for the detection of certain bacteria, parasites, and fungi. It is also used to detect protein kinase activity in cells or tissue samples. 4MUG can be conjugated to an enzyme or antibody to produce a fluorescent signal when activated by light at 350 nm. The compound has been shown to be nonfluorescent when in the dark, but will emit fluorescence upon activation with light at 350 nm.
