Patent number: 8399633Abstract: During the production of recombinant proteins from gram negative bacteria, lipopolysaccharides (LPS, endotoxin) are released along with the protein of interest. In many instances, LPS will copurify with the target protein due to specific or non-specific protein-ILPS interactions. We have investigated the ability of alkanediols to effect the separation of LPS from protein-LPS complexes while the complexes are immobilized on anion or cation exchange chromatographic media. Alkanediols provide a safer alternative to the use of other organics such as alcohols or acetonitrile due to their lower toxicity and decreased flammability. In addition, they are less costly than many of the detergents that have been used for such purposes. LPS removal efficiency increased with increasing alkane chain length. 1,2-alkanediols were more effective than terminal alkanediols in the separation of LPS from protein LPS complexes.Type: GrantFiled: May 19, 2010Date of Patent: March 19, 2013Assignee: Fujifilm Diosynth Biotechnologies U.S.A., Inc.Inventors: Philip Alfred Ropp, Michael Van Alen Murray

Patent number: 6989373Abstract: The present invention relates to a method for treating damaged or degenerated fat pads in a foot of a host in need thereof. The method comprises the step of injecting into the fat pad of the host a biocompatiable solution having physico-chemical and mechanical properties substantially similar to a fatty acid mixture normally present in a healthy fat pad.Type: GrantFiled: October 29, 2001Date of Patent: January 24, 2006Assignee: Bio Syntech Canada Inc.Inventor: Eric André DesRosiers

Patent number: 6767994Abstract: The present invention relates to a process for purifying a hydrophobic or amphiphilic compound, by first mixing a starting material containing the hydrophobic or amphiphilic compound with a first polymeric material, water and at least one of a second polymeric material and a surfactant, wherein the first polymeric material and the second polymeric material and/or surfactant are immiscible in the resulting primary aqueous solution. The process further comprises maintaining the primary aqueous solution for a period of time sufficient for essentially separating the phases formed, and then removing the phase containing the main portion of the hydrophobic or amphiphilic compound and the second polymeric material and/or surfactant. The second polymeric material and/or surfactant are separated from the hydrophobic or amphiphilic compound, and subsequently recycled to the initial mixing step.Type: GrantFiled: May 16, 2000Date of Patent: July 27, 2004Assignee: Pharmacia ABInventors: Hans Ageland, Lena Nyström, Josefine Persson, Folke Tjerneld

Patent number: 6610831Abstract: Methods and apparatus for recovering zein from substrates are disclosed. The method includes extracting a zein-containing substrate such as whole corn with ethanol to yield a crude zein alcoholic dispersion and treating this dispersion with an adsorbent to remove at least one of starch, color or oil to yield a purified zein which is subsequently recovered or used in industrial applications. A preferred adsorbent is activated charcoal.Type: GrantFiled: December 21, 1999Date of Patent: August 26, 2003Assignee: Lurgi PSI, Ltd.Inventors: Jerel McInnis, Qingnong Tang

Patent number: 6562952Abstract: A process for forming small micron-sized (1-10 &mgr;m) protein particles is provided wherein a protein, a solvent system for the protein and an antisolvent for the protein solvent system are contacted under conditions to at least partially dissolve the protein solvent system in the antisolvent, thereby causing precipitation of the protein. The solvent system is made up of at least in part of a halogenated organic alcohol, most preferably 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Preferably, a solution of the protein in the solvent system is sprayed through a nozzle into a precipitation zone containing the antisolvent (preferably CO2) under near- or supercritical conditions.Type: GrantFiled: October 31, 2000Date of Patent: May 13, 2003Assignee: The University of KansasInventors: Roger A. Rajewski, Bala Subramaniam, William K. Snavely, Fenghui Niu
