Abstract
The process for the separation of antiVIII:C antibodies present in a liquid consists of contacting said liquid with a solid support constituted by a polymer or a copolymer having in its chain substitutable groups, whereof at least part is substituted by groups having an affinity for antiVIII:C antibodies and a selectivity for antiVIII:C antibodies compared with other immunoglobulins and then separating the liquid from the support on which have been adsorbed the antiVIII:C antibodies. Preferably use is made of polystyrene, to which have been fixed groups --SO.sub.3 Na and --SO.sub.2 Glu, --SO.sub.2 Threo, --SO.sub.2 OHPro or SO.sub.2 Lys. These supports can be used for ex-vivo purification in the column of the blood plasma of a type A hemophiliac.
