Fluorescent Spot

Abstract I describe a fluorescent spot test for detecting the acidic glycosidases in meconium. Meconium is mixed with various 4-methylumbelliferylglycosides at the appropriate pH. In the presence of carbohydrate-splitting enzymes, 4-methylumbelliferone, a strongly fluorescent compound, is released. The reaction mixture, when spotted on chromatography paper and viewed under ultraviolet light, exhibits a bright fluorescence for specimens containing acidic glycosidases. The technique is applicable to any test that involves production of fluorescent products from non-fluorescent reactants. The procedure was applied to meconium specimens selected because of increased albumin content known to be associated with cystic fibrosis in newborns. The presence of beta-D-fucosidase in meconium was correlated to increased albumin content. Detection of beta-D-fucosidase by the present procedure may be useful as a screening test for cystic fibrosis.
