Catalog No: A10GD-4264
Cas No: 124223-99-0
Properties: Mol Formula: C18H21NO8, Mol Weight: 379.4
IUPAC Name: N-[(2R,3R,4R,5R,6R)-4,5-dihydroxy-6-(hydroxymethyl)-2-(4-methyl-2-oxochromen-7-yl)oxyoxan-3-yl]acetamide
Synonym: 2H-1-Benzopyran-2-one, 7-[[2-(acetylamino)-2-deoxy-alpha-D-galactopyranosyl]oxy]-4-methyl-, 4-Methylumbelliferyl 2-acetamido-2-deoxy-a-D-galactopyranoside, N-[(2R,3R,4R,5R,6R)-4,5-dihydroxy-6-(hydroxymethyl)-2-(4-methyl-2-oxochromen-7-yl)oxyoxan-3-yl]acetamide
A fluorogenic substrate for the detection of lysosomal enzyme N-acetyl-?-D-galactopyranosiaminidase (NAGA), which is driving the pathogenesis of Schindler disease. Also substrate for endo-?-N-acetylgalactosaminidase (O-glycosidase), which cleaves O-linked core 1 and core 3 disaccharides from glycoproteins.
4-Methylumbelliferyl 2-acetoamido-2-deoxy-?-D-galactopyranoside (4-MU-2-acetoamido-2-deoxy-?-Gal) is a fluorogenic substrate used to quantify ?- and ?-galactopyranosaminidase activity. 4-MU-2-acetoamido-2-deoxy-?-Gal is cleaved by ?- and ?-galactopyranosaminidase to release the fluorescent moiety 4-MU. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases.
