Abstract

On décrit des procédés de construction génétique et d'expression de protéines hybrides à base d'anticorps ayant une demi-vie circulante améliorée. Les protéines hybrides de l'invention sont incapables de se lier aux récepteurs pour le fragment Fc des immunoglobulines, soit en conséquence de l'utilisation de l'isotype des anticorps pour construire la protéine hybride, soit par mutagenèse dirigée des isotypes des anticorps qui se lient normalement aux récepteurs pour le fragment Fc. Les protéines hybrides de l'invention peuvent également contenir un domaine fonctionnel capable de lier un récepteur de protection des immunoglobulines.
