1.1.5.14	biotechnology	an automated, enzymatic insulin assay is developed. Principle: Fructose is produced by the action of inulinase on inulin present in the sample. The resulting fructose reacts with D-fructose dehydrogenase in the presence of the oxidized form of 1-methoxy-5-methylphenazinium methylsulfate (1-m-PMS) to produce the reduced form of 1-m-PMS. Reduced 1-m-PMS acts on dissolved oxygen to produce hydrogen peroxide, which, through the action of peroxidase, oxidatively condenses N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine and 4-aminoantipyrine to transform them into quinoneimine dye. The absorbance of the quinoneimine dye is measured spectrophotometrically to determine the concentration of inulin in the sample. The new enzymatic assay offers a more convenient and more accurate measurement of inulin and may be suitable for routine procedures by automated analyzers in clinical laboratories	703276	
1.1.5.14	biotechnology	multi-walled carbon nanotubes synthesized on platinum plate (MWCNTs/Pt) electrode are immediately immersed into solutions of FDH to immobilize the enzyme onto electrode surfaces. Thereafter, a well-defined catalytic oxidation current based on FDH is observed from ca. -0.15V, which is close to the redox potential of heme c as a prosthetic group of FDH. From an analysis of a plot of the catalytic current versus substrate, the calibration range for the fructose concentration is up to ca. 40 mmol/dm3, and the apparent Michaelis-Menten constant is evaluated to be 11 mmol/l. The obtained results are useful in applications to prepare the third-generation biosensors and other future bioelectrochemical devices	702780	
1.1.5.14	biotechnology	using fructose dehydrogenase-catalyzed conversion of d-fructose to 5-ketofructose, followed by quantitation of MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] formazan production by direct spectrophotometry, an assay to measure serum fructose concentration is developed. The fructose dehydrogenase-based enzymatic assay correlates highly with gas chromatography-mass spectroscopic analysis of serum fructose. The assay is highly specific, exhibits no cross-reactivity with other sugars and is easy to perform	706060
