PURIFIED PREPARATION OF MAMMALIAN URICASE, METHOD FOR ITS PREPARING, PREPARATION OF ACTIVE URICASE CONJUGATE AND PHARMACEUTICAL COMPOSITION Russian patent published in 2006 - IPC C07K1/14 C12N9/06 A61K38/44 A61P13/00 

Abstract RU 2281954 C2

FIELD: medicine, biochemistry, pharmaceutical industry, pharmacy.

SUBSTANCE: method involves separation of the mammalian enzyme uricase purified preparation for fractions followed by combination of fractions showing the absence of mammalian uricase aggregates exceeding octamer size based on data obtained in measurement of light scattering and ultraviolet absorption of these fractions. The prepared preparation is conjugated with poly-(ethylene glycol) or poly-(ethylene oxide) and used as a component of the pharmaceutical composition used for reducing of the concentration of uric acid in liquid or body tissue. Use of invention provides decreasing the immunogenic effect of uricase being without reducing its uricolytic effect.

EFFECT: improved preparing method, valuable medicinal and pharmaceutical properties of enzyme and pharmaceutical composition.
