Interference of sucrose with the fluorometric assay of tryptophan.
Sucrose has been found to decrease the fluorescence observed during the standard fluorometric assay of tryptophan. The quenching is enhanced with increasing concentrations of sucrose. This phenomenon is not due to a metal contaminant in the sucrose, nor to a direct interaction of the sugar with the fluorophore, norharman, which results from the oxidation of a tryptophanformaldehyde complex by F...
متن کاملFluorometric determination of histidine.
A. FLUOROMETRIC METHOD for the determination of histidine was developed in response to the need for an accurate and precise manual method for the confirmation of histidinemia (1). it is based on the fluorometric method of Shore et a!. (2), which involves the condensation of histaniine with o-phthalaidehyde (OPT) in a strongly alkaline solution to form a rather labile fluorescent compound which ...
متن کاملFluorometric determination of propoxyphene.
With 4-chloro-7-nitrobenzo-2, 1,3-oxadiazole (I), fluorescent derivatives of propoxyphene can be prepared, thus enabling quantitation of the drug in biological samples. This technique offers an acceptable alternative to gas chromatographic (1-5) or ultraviolet spectrophotometric (6, 7) procedures. Favorable aspects of the fluorometric technique are high sensitivity, specificity, potential for r...
متن کاملFluorometric determination of carbohydrate with 2-aminothiophenol.
The 2-aminothiophenol-based fluorometric assay of Nakano et al. (1973, J. Pharm. Soc. Jpn. 93, 350-353) for monosaccharides has been modified to improve the speed, applicability, and sensitivity of the method. The improved assay is applicable to complex carbohydrates as well as to monosaccharides. Less than 50 ng of carbohydrate in a final volume of 2 ml can be quantitatively measured within 30...
