    Abstract: PROBLEM TO BE SOLVED: To obtain a separating agent for solid-phase extraction which combines hydrophilicity and hydrophobicity, has a sharp distribution of particle sizes and allows low-cost manufacture with a high yield, and to provide its applications.
    SOLUTION: This separating agent consists of a core particle of a substrate, a hydrophilic polymer layer formed on the surface of the particle and a hydrophobic polymer layer formed on the surface of the hydrophilic polymer layer. A column or cartridge charged with the separating agent and a method for concentrating a target substance, a method for removing impurities, a method for solid-phase extraction of samples related to the environment, medicines or living bodies and a method for pretreating samples containing protein ingredients, with all the methods using the separating agent, are also provided.

    Abstract: PROBLEM TO BE SOLVED: To provide a variant xylytol dehydrogenase (XDH) having improved conversion efficiency of xylitol to xylulose by improving the coenzyme demand of wild XDH to nicotinamide adenine dinucleotide phosphate (NADP) type and improving the heat-resistance. SOLUTION: The coenzyme demand of a wild XDH is changed to NADP demand by substituting the 207th aspartic acid of the amino acid sequence to alanine, 208th isoleucine to arginine, 209th phenylalanine to threonine or tyrosine and 211th asparagine to arginine and the heat-resistance is improved by substituting the 96th serine to cysteine, the 99th serine to cysteine and 102nd tyrosine to cysteine and introducing a structure-stabilized zinc bonding site.

    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a biological substance chip capable of detecting and determining quantitatively a target biological substance using the biological substance chip without modifying the target biological substance by a labeled compound, and a detection and quantitative determination method for the target biological substance. SOLUTION: The biological substance chip coupled preliminarily with the detected biological substance by hybridization is manufactured for a probe biological substance immobilized on a substrate, the target biological substance is hybridized to the probe biological substance on the biological substance chip, the detected biological substance is eliminated therefrom, and a variation of a signal from the detected biological substance is measured before and after the hybridization of the target biological substance to conduct the detection and the quantitative determination. The target biological substance is detected and determined quantitatively without labeling the target biological substance. COPYRIGHT: (C)2004,JPO
