| 20080274138 | Formulation of Sugar Solutions for Continuous Ultracentrifugation for Virus Purification - The present invention provides a method for purification of a virus or virus antigen comprising providing a virus preparation and centrifugation of said virus preparation in a gradient of a sugar established by the addition of two or more buffered sugar layers of different concentration. The method leads to higher yields and reduces unwanted aggregation of the virus or virus antigen by increasing the volume of the peak pool. | 11-06-2008 |
| 20080286307 | Two-Step Temperature Profile for the Propagation of Viruses - The present invention provides a method for the production of a virus. The method includes providing a host cell that has been infected by the virus and cultivating the infected host cell at two different temperatures. The virus produced by the cultivation steps is subsequently collected. By using the dual temperature cultivation process, high titer and improved purity can be obtained. | 11-20-2008 |
| 20090181423 | SUBSTANTIALLY ANIMAL PROTEIN-FREE RECOMBINANT FURIN AND METHODS FOR PRODUCING SAME - The present invention relates to recombinant furin (rFurin) and methods for producing rFurin. More specifically, the invention relates to substantially animal protein-free rFurin and methods for producing substantially animal protein-free rFurin. | 07-16-2009 |
| 20100239606 | Two-Step Temperature Profile for the Propagation of Viruses - The present invention provides a method for the production of a virus. The method includes providing a host cell that has been infected by the virus and cultivating the infected host cell at two different temperatures. The virus produced by the cultivation steps is subsequently collected. By using the dual temperature cultivation process, high titer and improved purity can be obtained. | 09-23-2010 |
| 20100239609 | Formulation of Sugar Solutions for Continuous Ultracentrifugation for Virus Purification - The present invention provides a method for purification of a virus or virus antigen comprising providing a virus preparation and centrifugation of said virus preparation in a gradient of a sugar established by the addition of two or more buffered sugar layers of different concentration. The method leads to higher yields and reduces unwanted aggregation of the virus or virus antigen by increasing the volume of the peak pool. | 09-23-2010 |
| 20110076719 | Substantially Animal Protein-Free Recombinant Furin and Methods for Producing the Same - The present invention relates to recombinant furin (rFurin) and methods for producing rFurin. More specifically, the invention relates to substantially animal protein-free rFurin and methods for producing substantially animal protein-free rFurin. | 03-31-2011 |
| 20110081680 | Animal Protein-Free Media For Cultivation of Cells - The present invention relates to animal protein-free cell culture media comprising polyamines and a plant- and/or yeast-derived hydrolysate. The invention also relates to animal protein-free culturing processes, wherein cells can be cultivated, propagated and passaged without adding supplementary animal proteins in the culture medium. These processes are useful in cultivating cells, such as recombinant cells or cells infected with a virus, and for producing biological products by cell culture processes. | 04-07-2011 |
| 20110081722 | ANIMAL PROTEIN-FREE MEDIA FOR CULTIVATION OF CELLS - The present invention relates to animal protein-free cell culture media comprising polyamines and a plant- and/or yeast-derived hydrolysate. The invention also relates to animal protein-free culturing processes, wherein cells can be cultivated, propagated and passaged without adding supplementary animal proteins in the culture medium. These processes are useful in cultivating cells, such as recombinant cells or cells infected with a virus, and for producing biological products by cell culture processes. | 04-07-2011 |
| 20110086411 | Method of Producing a Polypeptide or Virus of Interest in a Continuous Cell Culture - Described herein is a chemostat-like continuous cell culture system that combines certain advantages of perfusion open systems and chemostat open systems to improve the culturing of mammalian cells, e.g., genetically modified cells, particularly in serum-free or chemically-defined media. The continuous culture system described herein involves culturing mammalian cells in a continuous cell culture system, which comprises a cell retention device, wherein the cell culture system has a dilution rate (D) of less than about 2 d | 04-14-2011 |
| 20110086413 | Cell Culture Medium For ADAMTS Protein Expression - The present invention provides culture mediums that are useful for the expression of ADAMTS proteins, such as ADAMTS13. Methods for the expression and purification of ADAMTS proteins are also provided. In some embodiments, the mediums and methods of the invention are useful for the expression of ADAMTS proteins having high specific activities. Also provided are ADAMTS, e.g., ADAMTS13, protein compositions with high specific activities, which are expressed and purified according to the methods provided herein. | 04-14-2011 |
| 20110151512 | OLIGOPEPTIDE-FREE CELL CULTURE MEDIA - The present invention relates to oligopeptide-free cell culture media comprising at least 0.5 mg/L of a polyamine and to methods for cultivating cells in said oligopeptide-free cell culture media comprising at least 0.5 mg/L of a polyamine. The invention also relates to methods for expressing at least one protein in a medium comprising at least 0.5 mg/L of a polyamine and to methods for producing at least one virus in a medium comprising at least 0.5 mg/L of a polyamine. | 06-23-2011 |
