The invention provides biologically active erythropoietin (EPO) conjugate compositions wherein a transglutaminase reaction is employed to covalently and site specifically conjugate the EPO molecule to a non-antigenic hydrophilic polymer that can also be covalently linked to an organic molecule either of which modification increases the circulating serum half-life of the composition.
L'invention concerne des compositions de conjuguées d'érythropoïétine (EPO) biologiquement actives. On utilise une réaction transglutaminase pour conjuguer la molécule d'EPO de manière covalente et régiospécifique à un polymère hydrophile antigénique pouvant également être lié par covalence à une molécule organique, l'une quelconque de ces modifications permettant d'augmenter la demi-vie sérique de la composition.
