Applications Phosphoglycolic Acid is used in studies pertaining to biological and metabolic processes. It can be used in the study of human apurinic/apyrimidinic endonuclease (Ape) and its role in double strand break repair. It also has been seen to complex with cPEPCK (cytosolic phosphoenolpyruvate carboxykinase) during the study of its inhibition by various substrate analogues.

PAIRED PRODUCT AVAILABLE: alpha-L-iduronidase Enzyme, FI179383.
4MU-alpha-L-idopyranosiduronic acid is a fluorogenic substrate for alpha-L-iduronidase. Active alpha-L-iduronidase cleaves the MU moiety from the synthetic substrate, which results in release of a fluorescent signal (Ex 360 nm / Em 455 nm). The reaction is stopped by the addition of sodium carbonate. 4MU-alpha-L-idopyranosiduronic acid is used in alpha-L-iduronidase assays in the context of biochemical characterisation of samples from patients affected by lysosomal storage disease mucopolysaccharidosis I (MPS I).
