SEPARATION OF PLASMA COMPONENTS

摘要

A method for separating components from plasma, the method comprising (I) separating the plasma into a first and second component by causing the first component to move through a first electrophoretic separation membrane under the influence of an electric potential, the first component comprising an albumin/.alpha.-1-antitrypsin pool and the second component comprising plasm a containing components having a molecular mass greater than albumin; (II) treating the second component under the influence of an electric potential i n the presence of a second electrophoretic separation membrane to form an immunoglobulins concentrate containing immunoglobulins substantially free fr om components having a molecular mass less than immunoglobulins; (III) treating the immunoglobulins concentrate under the influence of an electric potential in the presence of a third electrophoretic separation membrane to remove components having a molecular mass greater than immunoglobulins; and (IV) separating albumin and .alpha.-1-antitrypsin from the albumin/.alpha.-1- antitrypsin pool by causing .alpha.-1-antitrypsin to move through a fourth electrophoretic separation membrane under the influence of an electric potential.
