PROCESS FOR ISOLATING HUMAN ALBUMIN FROM SUPERNATANT IV, IN PARTICULAR IV-4, OR FROM COHN'S FRACTION V OR FROM AN ANALOGOUS SUPERNATANT OR FRACTION

摘要

The process for isolating albumin from super- natant IV, and in particular IV-4, or from COHN's frac- tion V or from a plasma supernatant or fraction of analogous composition derived from an alcoholic or non- alcoholic fractionation, comprises one step on a hydro- philic anion exchange column with binding of albumin to the column, and then elution, and one step on a hydro- phobic anion exchange column. Albumin thus obtained having a purity > 99% by cellulose acetate electro- phoresis, being free from impurities detected by crossed immunoelectrophoresis and free from polymers.
