    Abstract: Una composición seca que comprende los componentes: (a) una deshidrogenasa; (b) un cofactor redox; (c) un agente capaz de inducir un cambio en al menos una propiedad óptica de un reactivo indicador en presencia de equivalentes redox; (d) un reactivo indicador; y (e) al menos un soluto compatible que es ectoína o un derivado de la misma, en la que dicha deshidrogenasa es una glucosa deshidrogenasa y en la que dicho derivado de ectoína se selecciona entre el grupo que consiste en: hidroxiectoína, homoectoína, un éster de hidroxiectoína, un éter de hidroxiectoína, un derivado de sulfonilo de ectoína o un derivado de sulfonilo esterificado de ectoína y una amida de un derivado de sulfonilo de ectoína.

    Abstract: The present invention is concerned with means and methods for maintaining and preserving enzymatic activity. In particular, the invention relates to a dry composition comprising a dehydrogenase, a redox cofactor, an agent capable of eliciting at least one optical change in an optical property of an indicator reagent in the presence of redox equivalents, an indicator reagent, and at least one compatible solute being ectoine or a derivative thereof. The invention further contemplates a diagnostic test element for the determination of an analyte from a body fluid sample and a method for the manufacture of such a test element. Further envisaged by the present invention is the use of at least one compatibie solute as mentioned above for reducing a decrease of the enzymatic activity of at least one enzyme in a composition under dry conditions. Furthermore, contemplated is a method for determining the presence or amount analyte in a body fluid sample based on the test element according to the invention.
