A new assay has been developed for measuring residual alkaline phosphatase (ALP) activity in a wide variety of dairy products. The method proposed is simple, rapid and directly applicable to solid and liquid dairy samples. ALP in the test sample hydrolyzes a non fluorescent substrate, trifluoromethyl-beta-umbelliferone phosphate, to its highly fluorescent(More)
Theophylline is an effective bronchodilatator used in the treatment of asthma which requires frequent control because of its narrow therapeutic index. Over the past decade much attention has been dedicated to the peculiar properties of the inner water pools of AOT (sodium 2-bishexyl-ethyl sulfosuccinate) microemulsions as enzyme microreactors, yet few(More)
The fluorescence of tin(IV) complexed by 8-hydroxyquinoline-5-sulfonic acid (8-HQSA) has been studied in both aqueous and hydroorganic (acetate buffer and dimethylsulfoxide) media. Several experimental parameters such as pH, DMSO/water ratio and reactant concentration have been investigated to increase the fluorescence of the tin(IV)-8-HQSA complex. A(More)
