Provided herein are methods for the purification of recombinant adeno-associated virus (rAAV) vectors that can be used for gene transfer and specifically for gene therapy or vaccination. Recombinant AAV vectors of the invention are substantially free of in-process impurities, including production components such as cellular nucleic acids, cellular proteins, helper virus, and media components.

Methods for purification of recombinant AAV vectors

Methods, kits and apparatuses for chromatography purification of antibodies are provided. In some embodiments, antibodies are purified by mixed mode chromatography that does not comprise hydroxyapatite (HT) or fluorapatite (FT). The mixed mode chromatography step is then followed by a HT/FT chromatography step.

Chromatography purification of antibodies

Methods are disclosed for use of apatite chromatography, particularly without reliance upon phosphate gradients, for purification or separation of at least one intact non-aggregated antibody, or at least one immunoreactive antibody fragment, from an impure preparation. Integration of such methods into multi-step procedures with other fractionation methods are additionally disclosed.

Enhanced purification of antibodies and antibody fragments by apatite chromatography

This invention relates to the use of mixed mode chromatography for purification of at least one intact non-aggregated antibody from a mixture containing intact non-aggregated antibodies and undesirable materials, including fragmented or aggregated antibodies, host cell proteins, DNA, endotoxin, and/or virus. This invention further relates to the integration of such a method into a multi-step procedure with other fractionation methods for purification of antibodies suitable for in vivo applications.

Enhanced capacity and purification of antibodies by mixed mode chromatography in the presence of aqueous-soluble nonionic organic polymers

This invention relates to the use of mixed mode chromatography for purification of a protein from a mixture containing other materials, including fragmented or aggregated antibodies, host cell proteins, DNA, endotoxin, and/or virus. This invention further relates to the integration of such a method into a multi-step procedure with other fractionation methods for purification of antibodies or other proteins suitable for in vivo applications.
