Stabilization of the enzyme urate oxidase in liquid form.

摘要

This invention relates to a process for stabilizing the enzyme urate oxidase (commonly known as uricase) in liquid form, and to the relative compositions which can then be obtained, with particular reference to compositions containing a Trinder reagent. According to the process of the invention, uricase can be stabilized in liquid form by adding to the composition containing the enzyme a substituted or unsubstituted dicarboxylic acid containing from 2 to 5 carbon atoms, and preferably 4 or 5. Aspartic acid has shown to be particularly effective in providing said stabilizing activity in liquid uricase compositions containing a Trinder reagent. <IMAGE>
