Abstract
An aqueous composition includes (i) glutamate dehydrogenase from a bacterium of thegenus, (ii) a stabilizing compound that is a carboxylic acid having a carbon-based chain of at least three carbon atoms and comprising at least two —COOH groups, or a salt thereof, and (iii) any of a monosaccharide polyol, disaccharide polyol, or polymeric macromolecule in addition to the glutamate dehydrogenase. A process for stabilizing the glutamate dehydrogenase in order to maintain antigenic properties of the glutamate dehydrogenase includes stabilizing the glutamate dehydrogenase in the aqueous composition and maintaining the antigenic properties of the glutamate dehydrogenase during storage of the aqueous composition.
