FIELD: chemistry.
SUBSTANCE: material, selected from group, which consists of glass, covered with silicon dioxin, glass, covered with silicone, is used as material of internal wall of container, which includes (i) wall section and (ii) one or more closing partitions, which do not constitute part of said wall section, and which contains protein composition, which has domain with amine-end y-carboxyglutamine acid (Gla), with 9-12 residues Gla; where said material reduces inclination of said protein to be subjected to di-, oligo- and/or polymerisation.
EFFECT: improvement of water composition stability - stability of VIIa (FVlla) factor in water solutions, which is important for containing and temporary storage of liquid composition of protein, especially of protein water composition.
