With a spectrofluorometer, the length of the incubation time required in the fluorogenic assay was reduced to 12 h. The threshold emissions for reading the fluorogenic reaction by the spectrofluorometer were 5 and 10 U for lauryl tryptose broth media

Globoid cell leukodystrophy is an inherited metabolic disorder of the central nervous system caused by deficiency of the lysosomal enzyme galactocerebrosidase. Haematopoietic stem cell transplantation is the only available effective treatment. The engraftment from normal donors provides competent cells able

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.
