  • Publication number: 20120207771
    Abstract: The present invention provides methods and kits for assessing whether a subject is afflicted with an FR?-expressing cancer, methods and kits for predicting the progression of ovarian cancer in a subject afflicted with an FR?-expressing cancer, methods and kits for assessing the level of risk that a subject will develop an FR?-expressing cancer, and methods of stratifying a subject with an FR?-expressing cancer into cancer therapy groups. The methods involve determining the level of folate receptor alpha (FR?) which is not bound to a cell in a sample derived from the subject and comparing this level with the level of FR? in a control sample.

  • Publication number: 20080131427
    Abstract: Whole Genome Evolution Technology can be considered a broad tool for supporting the needs for scaleable manufacturing of therapeutic antibodies. Its random nature and in vivo mode of action separate this process from other complementary technologies, thus providing alternative solutions to improve a host cell's manufacturing performance. The speed with which a pre-existing production strain can be optimized makes this process suitable for satisfying the current need for rapid cell line optimization to produce faster growing cells exhibiting high titers of antibody at the preclinical, clinical or commercialization stage.

  • Publication number: 20030143586
    Abstract: The invention provides methods for identifying polymorphic markers for herbicide resistance in weeds and for generating herbicide susceptible and herbicide resistant weeds by mutagenizing weeds and comparing genetic differences between herbicide resistant and herbicide susceptible weeds. The methods may involve the inhibition of mismatch repair in the weeds through the introduction of dominant negative alleles of mismatch repair genes, through T-DNA insertional mutations, or the use of chemical inhibitors of mismatch repair. The invention also provides polymorphic markers of herbicide resistance and methods and kits to screen for herbicide resistant weeds, such as horseweed, goosegrass and rye grass.
