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).Formula:C16H17NaO11SPurezza:Min. 97 Area-%Colore e forma:White PowderPeso molecolare: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.Formula:C16H19NO10SNaPurezza:Min. 95%Colore e forma:PowderPeso molecolare:439.37 g/molN,N,N',N'-Tetramethyl-p-phenylenediamine dihydrochloride

CAS:Dehydroluciferin is a synthetic analogue of luciferin, which is naturally found in fireflies. It has a high resistance to degradation by the target enzymes and is used as a substrate in chemiluminescent assays. Dehydroluciferin reacts with luciferase to produce light that can be measured using a photomultiplier tube. The light emission is proportional to the amount of enzyme activity present in the sample and may be used to determine the presence of specific enzymes in test samples. This compound also reacts with disulfide bonds, which are found in proteins, such as cytochrome P450, that are involved in metabolism.Formula:C11H6N2O3S2Purezza:Min. 97.0 Area-%Peso molecolare:278.31 g/molRef: 3D-W-201759
