4-Methylumbelliferyl β-D-lactoside

Supplier: MARKER GENE TECHNOLOGIES MS

Fluorescent substrate for β-lactosidase or combined galactosidase and glucosidase activities.

  • Lactosidase substrate
  • Optimal fluorescence above pH 8-9

This fluorogenic lactosidase probe releases the bright blue fluorophore 4-methylumbelliferone (4-MU) in direct correlation to the β-lactosidase enzyme activity contained in the sample. The fluorescence is optimal at pH values above 8-9 and therefore development of the optimal fluorescence by addition of a basic buffer (stop buffer) is usually performed to both stop the enzyme reaction and develop the fluorescence.

Formula: C₂₂H₂₈O₁₃
MW: 500,453 g/mol
CAS Number: 84325-23-5
