Title
(EN) TREATING PROTEIN-CONTAINING LIQUIDS
(FR) TRAITEMENT DE LIQUIDES CONTENANT DES PROTEINES
Abstract
(EN)
Abnormal infective prion proteins are removed from liquids containing biologically active substances, particularly blood products, by filtration using a depth filter formed of a matrix comprising solid particles of porous material and having a pore size less than 6 microns. Preferably the filter is free of cationic or anionic charged material.
(FR)
On élimine des liquides contenant des substances à activité biologique, notamment des produits sanguins, les protéines prions infectieuses anormales en les filtrant au moyen d'un filtre à lit profond. Celui-ci est formé d'une matrice constituée de particules solides d'un matériau poreux, dans lequel la taille des pores est inférieure à 6 microns. De préférence, le filtre est dépourvu de matériau chargé cationique ou anionique.
