| 20120114742 | Polymer Conjugates with Decreased Antigenicity, Methods of Preparation and Uses Thereof - Methods are provided for the preparation of conjugates of a variety of bioactive components, especially proteins, with water-soluble polymers (e.g., poly(ethylene glycol) and derivatives thereof), which conjugates have reduced antigenicity and immunogenicity compared to similar conjugates prepared using poly(ethylene glycol) containing a methoxyl or another alkoxyl group. The invention also provides conjugates prepared by such methods, compositions comprising such conjugates, kits containing such conjugates or compositions and methods of use of the conjugates and compositions in diagnostic and therapeutic protocols. | 05-10-2012 |
| 20110287466 | Aggregate-Free Urate Oxidase for Preparation of Non-Immunogenic Polymer Conjugates - A naturally occurring or recombinant protein, especially a mutein of porcine urate oxidase (uricase), that is essentially free of large aggregates can be rendered substantially non-immunogenic by conjugation with a sufficiently small number of strands of polymer such that the bioactivity of the protein is essentially retained in the conjugate. Such conjugates are unusually well suited for treatment of chronic conditions because they are less likely to induce the formation of antibodies and/or accelerated clearance than are similar conjugates prepared from protein preparations containing traces of large aggregates. | 11-24-2011 |
