Abstract

A fast chromatographic procedure for the purification of the gamma-globulin fraction of human serum on ferric oxide-containing agarose has been developed. The presence of ferric oxide (to which gamma-globulin is absorbed) increases the rigidity of the beads. They can therefore be used at high flow rates without troublesome crosslinking. The separation has been performed on a 14-ml column and on a 1.5-ml disposable column. The yield is 87 +/- 6% and the gamma-globulin fraction is homogeneous in agarose gel electrophoresis.
