Provided herein are methods for purifying recombinant A Disintegrin-like and Metallopeptidase with Thrombospondin Type 1 Motif 13 (ADAMTS13) protein from a sample. The method comprises enriching for ADAMTS13 protein by chromatographically contacting the sample with hydroxyapatite under conditions that allow ADAMTS13 protein to appear in the eluate or supernatant from the hydroxylapatite. The methods may further comprise tandem chromatography with a mixed mode cation exchange/hydrophobic interaction resin that binds ADAMTS13 protein. Additional optional steps involve ultrafiltration/diafiltration, anion exchange chromatography, cation exchange chromatography, and viral inactivation. Also provided herein are methods for inactivating virus contaminants in protein samples, where the protein is immobilized on a support. Also provided herein are compositions of ADAMTS13 prepared according to said methods.

Methods of purifying recombinant ADAMTS13 and other proteins and compositions thereof

Adeno-associated liquid and lyophilized pharmaceutical compositions are provided herein. In exemplary aspects, the pharmaceutical compositions comprise about 5 mM to about 25 mM L-histidine, about 0 mM to about 150 mM sodium chloride, about 0.001% (w/v) to about 0.01% (w/v) polysorbate 80 (PS80), and about 1% to about 10% (w/v) sucrose, trehalose, or combination thereof to AAV. In exemplary aspects, the pharmaceutical compositions further comprise glycine or mannitol. Methods of preparing a pharmaceutical composition comprising AAV, methods of treating a bleeding disorder in a subject, and methods of storing AAV compositions are also provided.

Adeno-associated virus formulations

Provided herein are methods of producing an adeno-associated virus (AAV) product, methods of purifying adeno-associated virus, and methods of purifying full AAV capsids from a concentrated AAV fraction comprising empty AAV capsids and full AAV capsids.

Adeno-associated virus purification methods

Provided herein are methods of producing an adeno-associated virus (AAV) product and methods of purifying adeno-associated virus. AAV is loaded onto an affinity resin, wash steps are undertaken, and AAV is eluted from the affinity resin. Various buffers are disclosed for use in the wash steps and elution.

The present invention relates to a method for separating a mature von Willebrand Factor (mat-VWF) from von Willebrand Factor pro-peptide (VWF-PP) by incubating a composition comprising inducing dissociation of mat-VWF and VWF-PP by disruption of the non-covalently associated mat-VWF and VWF-PP, wherein said dissociation is induced by: (i) addition of at least one chelating agent, or (ii) increasing the pH to a pH of at least 7, and then collecting said mat-VWF to obtain a high purity, propeptide depleted mature VWF (mat-VWF).
