4-Methylumbelliferyl-α-L-iduronide 2-sulfate (sodium)
4-Methylumbelliferyl-α-L-iduronide 2-sulfate (4-MU-α-idoa 2-sulfate) sodium is a fluorogenic substrate of iduronate-2-sulfatase (I2S). 4-Methylumbelliferyl-α-L-iduronide 2-sulfate sodium can be hydrolyzed by lysosomal enzyme α-l-iduronidase (IDUA) and release the fluorophore 4-Methylumbelliferone (HY-N0187). 4-Methylumbelliferyl-α-L-iduronide 2-sulfate sodium can be used to detect Hurler syndrome.
