| 20110293650 | INFLUENZA VIRUS-LIKE PARTICLES (VLPS) COMPRISING HEMAGGLUTININ - A method for synthesizing influenza virus-like particles (VLPs) within a plant or a portion of a plant is provided. The method involves expression of influenza HA of type A/California/04/09 in plants and the purification by size exclusion chromatography. The invention is also directed towards a VLP comprising influenza HA protein of type A/California/04/09 and plants lipids. The invention is also directed to a nucleic acid encoding influenza HA of type A/California/04/09 as well as vectors. The VLPs may be used to formulate influenza vaccines, or may be used to enrich existing vaccines. | 12-01-2011 |
| 20110104753 | Soluble Recombinant Influenza Antigens - The present invention provides a recombinant soluble trimeric hemagglutinin (rHA) protein comprising a hemagglutinin ectodomain and an oligomerization domain. The rHA is produced as a soluble homotrimer, and may further comprises a signal peptide and/or an endoplasmic reticulum (ER) retention signal. The invention is also directed to nucleic acids encoding the rHA of the invention, as well as vectors and chimeric constructs comprising the nucleic acid. Methods of producing the rHA are also provided. The rHA described herein may be used to formulate influenza vaccines, or may be used to enrich existing vaccines. | 05-05-2011 |

| 20090318377 | MEDICAGENIC ACID SAPONIN AND USES THEREOF - A cholesterol-lowering preparation comprising medicagenic acid saponin is disclosed. The amount of medicagenic acid saponin in the preparation is greater than 50% by weight to produce the cholesterol-lowering effect in an animal. A method of purifying a preparation of at least 30% medicagenic acid saponin is also disclosed. The preparation may be purified from alfalfa plants and used as a treatment for lowering cholesterol and triglycerides in an animal, in particular a human. | 12-24-2009 |
