  • Patent number: 8003847
    Abstract: The genome of the non-human mutant mammal, deficient in an endogenous Sigma receptor, contains a mutation that comprises a disruption in an endogenous Sigma receptor gene, wherein said gene disruption gives rise to a mutant lacking detectable levels of endogenous Sigma receptor. The mutant may be used as a control animal for in vivo tests, as well as a source of cells that can be used in in vitro tests. Mutants deficient in the Sigma-1 receptor can be used as models for in vivo study of disorders of the central nervous system, memory alterations, stress conditions and drug addictions, analgesia processes and neuroprotection. Mutants deficient in the Sigma-2 receptor can be used to study diagnostic or therapeutic tools to fight cancer and/or degenerative processes and/or to design compounds capable of preventing, reducing or alleviating the secondary pathology associated with administration of neuroleptic agents.

  • Patent number: 7732659
    Abstract: The present invention provides systems that allow reliable multiplexed transformation of Drosophila embryos. The present invention provides methods and reagents that allow preparation of injection-quality nucleic acid samples and that allow simultaneous preparation of multiple such samples. The present invention provides systems for simultaneous processing of multiple injected embryos. The present invention provides methods for transformation of Drosophila embryos involving use of virginator strains that can be used to increase the efficiency of setting up the crosses needed to produce the eggs for the injections and for the crosses needed to screen for transformants.

  • Patent number: 7709695
    Abstract: A transgenic non-human animal expressing at least one transgene including a DNA sequence encoding a heterologous Amyloid Precursor Protein (APP) including at least the Arctic mutation (E693G) and a further AD (Alzheimer's disease) pathogenic mutation or a further transgene affecting AD pathogenesis, which results in increased amounts of intracellular soluble A aggregates, including A peptides. The method of producing the transgenic animal, and methods of screening for therapeutic or diagnostic agents useful in treatment or diagnosis of Alzheimer's disease are also disclosed.

  • Patent number: 7700825
    Abstract: The present invention relates to the method and use of reef coral fluorescent proteins in making transgenic red, green and yellow fluorescent zebrafish. Preferably, such fluorescent zebrafish are fertile and used to establish a population of transgenic zebrafish and to provide to the ornamental fish industry for the purpose of marketing. Thus, new varieties of ornamental fish of different fluorescence colors from a novel source are developed.

  • Patent number: 7663019
    Abstract: A transgenic animal such as a transgenic snake or other reptile that expresses a heterologous expression product is described, along with methods of making the same. In general, the animal comprises cells containing a sequence encoding the heterologous expression product. The sequence encoding the heterologous expression product is integrated into the genome of the animal (e.g., in some or all cells thereof, and in some embodiments into germ cells thereof). The sequence encoding the heterologous expression product is, in general, operatively associated with an expression sequence or promoter. The animals are useful for, among other things, testing of repellents, testing of toxicological compounds, as teaching aids, for venom production, etc.

  • Patent number: RE42704
    Abstract: Materials and methods for producing fibrinogen in transgenic non-human mammals are disclosed. DNA segments encoding A?, B? and ? chains of fibrinogen are introduced into the germ line of a non-human mammal, and the mammal or its female progeny produces milk containing fibrinogen expressed from the introduced DNA segments. Non-human mammalian embryos and transgenic non-human mammals carrying DNA segments encoding heterologous fibrinogen polypeptide chains are also disclosed.
