PROCESS FOR THE PURIFICATION OF A POLYPEPTIDE OR PROTEIN USING IMMOBILISED PHOSVITIN, REMOVAL OF METAL IONS FROM BIOLOGICAL MATERIAL

摘要

Phosvitin or a modified phosvitin (for example by trypsin digestion) immobilised and coupled to a suitable matrix may be used for the separation and purification of proteins or polypeptides and in the removal of metal ions from biological material. If desired the phosvitin or modified phosvitin may be in the form of a metal chelate complex. This chelate may be used to remove peroxide from solvents.
