Product Introduction
4-Methylumbelliferyl β-D-Galactopyranoside-6-sulfate (4-MU-Gal-6S) is a fluorogenic substrate for N-acetylgalactosamine-6-sulphatase (GALNS). 4-MU-Gal-6S is cleaved by GALNS to release the fluorescent moiety 4-MU. 4-MU fluorescence intensity increases as pH decreases. It has been used to detect Morquio disease type A, a lysosomal storage disorder in which GALNS is deficient.
