4-MU-α-GlcNS sodium 

4-MU-α-GlcNS sodium is a fluorogenic substrate of heparin sulphamidase, is desulfurized into 4-MU-α-GlcNH₂. 4-MU-α-GlcNH₂ can liberate 4-methylumbelliferone (4-MU, fluorescent product) via α-glucosaminidase catalysis, with the emission wavelength maxima of 445-454 nm. 4-MU-α-GlcNS sodium can be used to heparin sulphamidase deficiencies associated with Mucopolisaccaridosis IIIA and other lysosomal disorders researches^[1][2][3].
