FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology and immunology. Disclosed herein a method for the isolation and purification of anti- IL-13 antibodies wherein the use of an affinity chromatographic step results in an antibody composition sufficiently pure for pharmaceutical uses. Method comprises pH viral reduction/inactivation, ultrafiltration/diafiltration, affinity chromatography, ion exchange chromatography, and hydrophobic chromatography.
EFFECT: further, the present invention is directed toward pharmaceutical compositions comprising one or more antibodies of the present invention.
