METHOD FOR IMPROVING STABILITY OF COMPOSITION CONTAINING FLAVIN-DEPENDENT LACTATE DEHYDROGENASE

Provided is a method for improving thermal stability of a composition comprising flavin-dependent lactate dehydrogenase (LDH). The composition comprising LDH is allowed to coexist with one or more of an anion selected from the group consisting of a monocarboxylic acid, a dicarboxylic acid, a tricarb...

Beschreibung
Zusammenfassung:	Provided is a method for improving thermal stability of a composition comprising flavin-dependent lactate dehydrogenase (LDH). The composition comprising LDH is allowed to coexist with one or more of an anion selected from the group consisting of a monocarboxylic acid, a dicarboxylic acid, a tricarboxylic acid, a tetracarboxylic acid, a polycarboxylic acid, phosphoric acid, sulfuric acid or a salt thereof; a monosaccharide; a disaccharide; a nonionic polymer; and an ionic polymer. It is possible to reduce deactivation of LDH during preparation and storage of a lactate measuring reagent, a lactate assay kit, a lactate sensor and fuel cell, reduce the amount of LDH to be used; as well as improve thermal stability, storage stability and measurement accuracy of the measuring reagent, assay kit and sensor.
