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