Use of mixed dispersion of fluorescent galactosylceramide and sodium dodecylsulfate for assaying galactosylceramide-beta-galactosidase and diagnosing Krabbe disease.
A fluorescent derivative of galactosylceramide [NBD-GalCer: 12-N-methyl-N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)aminodecanoyl+ ++ galactosylceramide] was dispersed in sodium dodecylsulfate and used to determine the activity of galactosylceramide-beta-galactosidase. Optimal assay conditions were defined, compared to other assay procedures and found suitable for diagnosing Krabbe disease.
