CAS:4-MU-Gal-6S (M4A) is a fluorogenic substrate of galactose-6-sulfate sulfatase (GALNS), used for the diagnosis of Mucopolysaccharidosis IV type A (MPS IV A). MPS IV, also known as Morquio syndrome, is a rare metabolic disorder in which the human body cannot process glycosaminoglycans (GAGs). MPS IV A is caused by the deficiency of the enzyme N-acetyl-galactosamine-6-sulfatase resulting in accumulation of keratan and chondroitin sulfate in tissues. M4A is used as the GALNS substrate in the anti-lysosomal enzyme antibody assay for the treatments of lysosomal storage disorders (LSDs) with enzyme replacement therapies (ERTs).Fórmula:C16H17NaO11SPureza:Min. 97 Area-%Cor e Forma:White PowderPeso molecular:440.36 g/mol4-Methylumbelliferyl 2-deoxy-2-sulfamino-b-D-glucopyranoside sodium salt
4-Methylumbelliferyl 2-deoxy-2-sulfamino-beta-D-glucopyranoside sodium salt is a fluorogenic substrate for N-sulfoglucosamine sulfohydrolase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl 2-deoxy-2-sulfamino-beta-D-glucopyranoside sodium saltas a substrate for measuring the N-sulfoglucosamine sulfohydrolase activity is used for screening of Mucopolysaccharidosis IIIA (MPS IIIA) and diagnosis of Sanfilippo A syndrome.Fórmula:C16H19NO10SNaPureza:Min. 95%Cor e Forma:PowderPeso molecular:439.37 g/molN,N,N',N'-Tetramethyl-p-phenylenediamine dihydrochloride
