Abstract RU 2443426 C2

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to pharmacology and medicine and represents urate oxidase (uricase) conjugates for reduction in high uric acid levels in fluids and tissues of a mammal body, containing purified uricase and polyethylene glycol (PEG) in which at least 90% of said uricase represents a tetramer, and each subunit of said uricase is covalently bound with in average at most 12 polyethylene glycol filaments having a molecular weight approximately from 5 kDa to approximately 100 kDa.

EFFECT: invention provides elimination of urate oxidase immunogenicity with no impairment of uric acid decomposition activity.
