Abstract

La présente invention concerne des variantes du facteur plasminogène tissulaire qui font preuve d'une amélioration notable de la stimulation de la fibrine, d'une discrimination considérablement accrue entre cofacteurs de la fibrine, d'une résistance marquée à l'inhibition par PAI-1, et d'une zymogénicité sensiblement accrue, une combinaison de propriétés qui renforcent l'utilité thérapeutique de l'enzyme.
