The invention provides a method for producing a sterile and pyrogen-free column coupled to protein for use in removing a predetermined substance from the blood of a human subject. The method abrogates sterilization of the finished protein-containing product by providing sterile and pyrogen-free raw materials at each production step. The method provides a pathogen-free, purified solution of protein which binds to a predetermined substance in human blood such as LDL or immunoglobulin. Typically, the protein is anti-human LDL immunoglobulin or anti-human Ig immunoglobulin. The method also provides a sterile and pyrogen-free column matrix material such as an agarose which is chemically activated, either using CNBr and triethylamine or using 1,1'-carbonyldiimidazole. The sterile and pyrogen-free, activated matrix material and the pathogen-free, purified protein solution are combined under aseptic conditions to effect the coupling of the protein to the matrix material, and the protein-coupled matrix material is filled under aseptic conditions into a sterile and pyrogen-free housing to produce a sterile and pyrogen-free column.

L'invention porte sur un procédé de production d'une colonne stérile et apyrogène couplée à une protéine en vue de l'extraction d'une substance donnée du sang d'un patient qui rend inutile la stérilisation du produit fini à base de protéine en ne fournissant que des produits de base stériles et apyrogènes lors de chacune des étapes du processus. Ledit procédé utilise une solution non pathogène purifiée de protéine qui se fixe à l'un des constituants du sang tel que la LDL (lipoprotéine de basse densité) ou l'immunoglobuline et plus particulièrement la protéine est une immunoglobuline LDL antihumaine ou une immunoglobuline Ig antihumaine, et un matériau matriciel apyrogène de colonne tel que de l'agarose activé chimiquement soit par du CNBr et de la triéthylamine, soit par du 1,1'-carbonyldimidazole. Le matériau matriciel stérile et apyrogène activé ainsi que la solution de protéine purifiée sont combinés dans des conditions d'asepsie pour assurer la fixation de la protéine sur le matériau matriciel et le matériau résultant est rempli dans des conditions d'asepsie dans un logement stérile et apyrogène ce qui permet d'obtenir une colonne stérile et apyrogène.
