20080249286 | HIGH-PRESSURE REFOLDING OF PROTEINS IN THE PRESENCE OF BINDING PARTNERS - Methods for producing biologically active protein from aggregated and/or denatured proteins which comprise subjecting the protein to high hydrostatic pressure in the presence of a ligand or specific binding agent are disclosed. The ligand can be a macromolecule, such as another protein, a nucleic acid, or other macromolecules, or the ligand can be a small organic molecule. | 10-09-2008 |
20090076247 | HIGH PRESSURE REFOLDING OF MONOCLONAL ANTIBODY AGGREGATES - Methods for refolding antibodies, particularly monoclonal antibodies, from aggregated and/or denatured preparations by subjecting the antibody preparation to high hydrostatic pressure are provided. Refolded preparations of antibodies produced by the methods described herein are also provided. | 03-19-2009 |
20090215998 | DEVICES AND METHODS FOR HIGH-PRESSURE REFOLDING OF PROTEINS - Disclosed are devices for holding samples, particularly liquid samples, during high-pressure treatment. The devices enable a variety of functions, such as high-throughput screening of samples in multi-compartment device embodiments, and adjustment of solution conditions during high-pressure treatment. The devices are designed to maintain integrity during the high-pressure conditions, and are optionally substantially impermeable to oxygen. | 08-27-2009 |
20100075399 | METHODS FOR PROTEIN REFOLDING - The present invention discloses improved methods of disaggregating protein aggregates, and refolding denatured proteins, using high pressure. In particular, the present invention provides for the use of agitation, high temperature, “stepped” depressurization, dialysis and dilution under pressure to increase the speed and extent of aggregate dissolution and protein refolding. | 03-25-2010 |
20100158951 | Method of Preparing an Immunologically-Active Adjuvant-Bound Dried Vaccine Composition - The disclosure provides a method of preparing an immunologically-active adjuvant-bound freeze dried vaccine composition. A specific embodiment provides a stable vaccine composition comprising an aluminum-salt adjuvant, a recombinant | 06-24-2010 |
20100255536 | HIGH PRESSURE REFOLDING OF PROTEIN AGGREGATES AND INCLUSION BODIES - The present disclosure provides an effective method for the refolding of denatured proteins in solution so that properly folded, biologically active protein in solution is recovered in high yield. The refolding takes place at pressures between about 0.25 kbar to about 3.5 kbar, advantageously at about 1.5 kbar to about 3 kbar. Typically a chaotropic agent is present at a concentration which is not effective for denaturing protein at atmospheric pressure, and optionally, oxidation-reduction reagents can be incorporated in the refolding solution so that native intramolecular disulfide bonds can be formed where that is desired. The method is applicable to substantially all proteins, especially after solubilization and/or denaturation of insoluble protein aggregates, inclusion bodies, or abnormal oligomeric (soluble) aggregates. | 10-07-2010 |
20100330162 | Spray freeze dry of compositions for pulmonary adminstration - This invention provides methods and compositions to preserve bioactive materials, such as viruses, bacteria, cells, or liposomes, in freeze dried particles suitable for pulmonary administration. Methods provide spray freeze drying of formulations to form stable freeze dried particles. | 12-30-2010 |
20110046357 | HIGH PRESSURE REFOLDING OF PROTEIN AGGREGATES AND INCLUSION BODIES - The present disclosure provides an effective method for the refolding of denatured proteins in solution so that properly folded, biologically active protein in solution is recovered in high yield. The refolding takes place at pressures between about 0.25 kbar to about 3.5 kbar, advantageously at about 1.5 kbar to about 3 kbar. Typically a chaotropic agent is present at a concentration which is not effective for denaturing protein at atmospheric pressure, and optionally, oxidation-reduction reagents can be incorporated in the refolding solution so that native intramolecular disulfide bonds can be formed where that is desired.

Methods provide spray freeze drying of formulations to form stable freeze dried particles for intranasal administration. | 10-06-2011 |
20120070406 | THERAPEUTIC PROTEIN COMPOSITIONS HAVING REDUCED IMMUNOGENICITY AND/OR IMPROVED EFFICACY - The present invention provides methods for reducing and/or evaluating the immunogenic potential of a therapeutic protein preparation. The present invention further provides pharmaceutical compositions of therapeutic proteins and methods of treatment with the same, the compositions having low immunogenic potential and/or improved efficacy. The invention achieves these goals by evaluating therapeutic protein preparations for subvisible protein particulates, which can contribute significantly to the overall immunogenic potential of the protein preparation. Further, by maintaining the content of such subvisible protein particulates to below an immunogenic threshold level, the resulting pharmaceutical composition is less likely to result in a loss of tolerance (e.g., upon repeated administration), thereby improving both the safety and efficacy profile of the therapeutic. | 03-22-2012 |
20120134958 | HYDROXYETHYL STARCH-CONTAINING POLYPEPTIDE COMPOSITIONS - The invention provides compositions containing hydroxyethyl starch and polypeptides, including therapeutic polypeptides such as interleukin-11, that provide for enhanced stability of the polypeptide following storage at room temperature or elevated temperatures. | 05-31-2012 |
