20120070893 | METHODS FOR PRODUCING NONADHERENT AVIAN CELL LINES - The present invention relates to a method for producing avian cell lines, comprising gradual or complete withdrawal of growth factors, serum and/or feeder layer so that the established lines are adherent or nonadherent cells capable of proliferating indefinitely in a basic culture medium. The invention also relates to the cells derived from such lines which are particularly useful for the production of substances of interest. | 03-22-2012 |
20110294209 | METHODS FOR PRODUCING NONADHERENT AVIAN CELL LINES - The present invention relates to a method for producing avian cell lines, comprising gradual or complete withdrawal of growth factors, serum and/or feeder layer so that the established lines are adherent or nonadherent cells capable of proliferating indefinitely in a basic culture medium. The invention also relates to the cells derived from such lines which are particularly useful for the production of substances of interest. | 12-01-2011 |
20110251085 | IN VITRO METHOD TO DETERMINE WHETHER A DRUG CANDIDATE ACTIVE AGAINST A TARGET PROTEIN IS ACTIVE AGAINST A VARIANT OF SAID PROTEIN - The present invention relates to the field of virology. More precisely, the invention provides a method of determining the ability of a test compound to modulate the biological activity of a variant of a target protein, wherein said test compound is previously known to modulate the biological activity of said protein. This invention is useful to determine whether a drug candidate, such as anti-viral compounds (eg. against hepatitis C virus: NS5B, NS3), active against a target protein is active against a variant of said protein (eg. polymorphisms, genotypes or mutants). | 10-13-2011 |
