Abstract

Procédé de greffage d'un élément fibreux pour l'élimination d'anticorps du sang ou d'un composant sanguin Procédé de greffage d'un élément fibreux pour l'élimination d'anticorps du sang ou d'un composant sanguin, ledit élément fibreux portant des fonctions acides carboxyliques, ledit procédé prévoyant d'imprégner un élément fibreux portant des fonctions acides carboxyliques avec une solution de greffage comprenant au moins un dérivé d'oligosaccharide capable de se lier à un ou plusieurs anticorps, ledit dérivé d'oligosaccharide portant au moins une fonction amine, de sorte à assurer un pontage covalent par formation d'une liaison amide entre le dérivé d'oligosaccharide et ledit élément fibreux, la solution de greffage comprenant ledit dérivé d'oligosaccharide solubilisé dans un solvant organique.
