CAS :4-Methylumbelliferyl 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranoside is a fluorogenic substrate for alpha-L-fucosidase. 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 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranosideas a substrate for measuring the alpha-L-fucosidase activity is used for fucosidosis diagnosis and in screening studies of glycoprotein metabolism disorders.Formule :C22H28O12Degré de pureté :Min. 95 Area-%Couleur et forme :PowderMasse moléculaire :484.45 g/mol4-Methylumbelliferyl b-D-xylopyranoside

The optimum concentration for this enzyme form is 10 nM for dopamine β-hydroxylase and 20 nM for brain functions. Mouse monoclonal antibodies against 5FITC have also been developed to detect the presence of toll-like receptor 4 (TLR4) on macrophages in vivo. 5FITC has also been used as a fluorescence probe for human immunoglobulin G (IgG) and erythrocytes in blood samples. Colloidal gold conjugates with 5FITC have been developed to measure the disulfide bonds in proteins such as human serum albumin.Formule :C21H11NO5SDegré de pureté :Min. 95%Masse moléculaire :389.38 g/mol4-Methylumbelliferyl a-D-arabinopyranoside
