Alpha-galactosidase A hydrolyzes the terminal alpha-galactosyl moieties from glycolipids and glycoproteins in lysosomes. Mutations in alpha-galactosidase cause lysosomal accumulation of the glycosphingolipid, globotriaosylceramide, which leads to Fabry disease. Small-molecule chaperones that bind to mutant enzyme proteins and correct their misfolding

The capability of HeLa cells to internalize large spherical microparticles has been evaluated by using inorganic, magnetic microparticles of 1 and 2.8 µm of diameter. In both absence but especially under the action of a magnet, both types of particles were

This study illustrates how optimization of both liquid-handling accuracy and precision is critical to assay performance. The study was designed to examine (1) liquid-handling performance and (2) the effect of liquid-handling variability on two types of in vitro biochemical assays

Fabry disease is an X-linked recessive disorder caused by the loss of function of the lysosomal enzyme α-Galactosidase-A. Although two enzyme replacement therapies (ERTs) are commercially available, they may not effectively reverse some of the Fabry pathology. PRX-102 is a

A fluorometric assay of lectin binding to yeast cells is reported. The relative amount of biotinylated lectins bound to the yeast cells was estimated by enzyme activity using 4-methylumbelliferyl-beta-D-galactoside as a substrate for the lectin-bound beta-galactosidase through biotin-avidin interaction.
