Abstract

Official abstract text for this publication.

One subject of the present invention is the use of a combination of a polyol (i) consisting of 12 carbon atoms and of a polyol (ii) consisting of 4 to 6 carbon atoms, as protein stabilizer. Another subject of the present invention is protein compositions comprising such a combination. A final subject of the present invention is a process for preparing protein compositions using such a combination.

First claim

Opening claim text (preview).

The invention claimed is: 1. A process of stabilizing proteins, comprising adding to a protein to be stabilized a combination of a polyol (i) consisting of 12 carbon atoms and of a polyol (ii) consisting of 4 to 6 carbon atoms, wherein said protein to be stabilized is a therapeutic protein selected from the group consisting of enzymes, cytokines, hormones, growth factors, plasma factors, vaccines, and antibodies, or is an enzyme intended for industrial use, and subjecting said protein to be stabilized to at least one of cryogenization, lyophilization treatments, and storage, wherein the polyol (i) is maltitol, and wherein a dry weight ratio of said polyol (i) to said polyol (ii) ranges from 50/50 to 75/25. 2. The process according to claim 1 , wherein said polyol (ii) comprises at least one of sorbitol, xylitol, and mannitol. 3. A process for preparing a protein composition comprising mixing together a protein, a polyol (i) consisting of 12 carbon atoms, and of a polyol (ii) consisting of 4 to 6 carbon atoms, wherein said protein is a therapeutic protein selected from the group consisting of enzymes, cytokines, hormones, growth factors, plasma factors, vaccines, and antibodies, or is an enzyme intended for industrial use, and subjecting said protein composition to at least one of cryogenization, lyophilization treatments, and storage, wherein the polyol (i) is maltitol, and wherein a dry weight ratio of said polyol (i) to said polyol (ii) ranges from 50/50 to 75/25. 4. The process according to claim 1 , wherein said protein to be stabilized is selected from the group consisting of erythropoietin, insulin, monoclonal antibodies, and growth hormones. 5. The process according to claim 1 , wherein said protein to be stabilized is a β-amylase.
