Abstract
A method for separating components from plasma, the method comprising (I) separating the plasma into a first and second component, the first component comprising an albumin/α-1-antirypsin pool and the second component comprising plasma containing components having a molecular mass greater than albumin; (II) treating the second component to form an immunoglobulins concentrate containing immunoglobulins substantially free from components having a molecular mass less than immunoglobulins; (III) treating the immunoglobulins concentrate to remove components having a molecular mass greater than immunoglobulins; and (IV) separating albumin and α-1-antitrypsin from the albumin/α-1-antitrypsin pool.
