  • Method of separating albumin from serum by ion-exchange chromatography with membrane adsorbers
    Patent number: 6001974
    Abstract: A method of separating albumin from serum by ion exchange chromatography with membrane adsorbers characterized by high productivity and yields of high purity albumin. The separation of the albumin is carried out on highly basic anion exchange membranes and on highly acidic cation exchange membranes. The albumin fraction can be eluted from the anion exchange membrane such that it can be fed directly to the cation exchange membrane without any special conditioning and the albumin can be extracted therefrom as an end product.
