Patent application numberDescriptionPublished
20080248522HIGH-PRESSURE INCLUSION BODY SOLUBILIZATION AND PROTEASE CLIPPING OF RECOMBINANT FUSION PROTEINS - Described herein are methods for the solubilization and proteolytic cleavage of fusion protein aggregates, including autocatalytic fusion proteins, at pressures greater than atmospheric pressure to yield soluble target polypeptides.10-09-2008
20080249286HIGH-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
20100075399METHODS 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
20100158951Method 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
20100255536HIGH 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
20100330162Spray 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
20110046357HIGH 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.

20110243996Spray freeze dry of compositions for intranasal administration - This invention provides methods and compositions to preserve bioactive materials, such as peptides, nucleic acids, viruses, bacteria, cells, or liposomes, in freeze dried particles suitable for intranasal administration. Methods provide spray freeze drying of formulations to form stable freeze dried particles for intranasal administration.10-06-2011
