Abstract
A polypeptide is extracted from an aqueous solution by a process in which a water-soluble macromolecular complex (I) of macromolecules covalently boned to molecules of at least one compound capable of fixing the polypeptide in a selective, reversible and non-destructive manner, is selectively reacted with the polypeptide in the solution to fix the polypeptide by forming in solution a complex (II); and the complex (II) is separated from the solution and dissociated into polypeptide molecules and complex (I) molecules, and the polypeptide is isolated.

A process for extracting a polypeptide from an aqueous solution, in which a dissolved water-soluble macromolecular complex (I) of macromolecules covalently bonded to molecules of at least one compound capable of fixing the polypeptide in a selective, reversible and non-destructive manner, is selectively reacted with the polypeptide in the solution to fix the polypeptide by forming, in solution, a complex (II);
- and the complex (II) is separated from the solution, then dissociated into polypeptide molecules and complex (I) molecules, and the polypeptide is isolated.
