摘要:
Maltooligosaccharide derivatives represented by the general formula: wherein at least one of R¹ and R² denotes a radical represented by: R³-S(O) m -R⁴ or R³-CO-R⁴, and the rest of them denotes hydrogen atom, an alkyl radical containing 1 to 6 carbon atoms or a phenyl radical, in which R³ is an alkyl radical containing 1 to 5 carbon atoms, R⁴ is an alkylene radical containing 1 to 5 carbon atoms, and m is 1 or 2, R⁵ denotes a substituted or non-substituted phenyl radical, and n denotes an integer of 1 to 8 ; and reagents comprising the maltooligosaccharide derivatives.
摘要:
A method for determining dehydrogenase or its substrate in dehydrogenase reaction, which comprises subjecting a dehydrogenase and its substrate to a dehydrogenase reaction in the presence of an electron carrier or a combination of a coenzyme and an electron carrier, allowing to form H₂O₂ through transfer of electrons derived from the substrate by the dehydrogenase reaction to O₂ via the electron carrier or via the coenzyme and electron carrier, stopping the dehydrogenase reaction, reacting said H₂O₂ with a peroxidase and a chromogen, and measuring a formed dye, and a reagent for determining dehydrogenase or its substrate. By the method and the reagent, dehydrogenase or its substrate can be accurately determined in a short time regardless of the concentration of the dehydrogenase and/or the substrate and without staining tubes or cells of a determination device with a dye.
摘要:
A method for measuring the amount of polyamines in a biological sample is provided. The method comprises utilizing diamine oxidase and/or polyamine oxidase, aminoalkylaldehyde dehydrogenase and NAD⁺ or NADPH⁺, and is carried out in the presence of an acidic aromatic compound.
