  • Patent number: 6794188
    Abstract: Recombinant avian sarcoma leukosis virus (ASLV)-derived retrovirus vectors having an expanded host range are described. The host range is expanded by the replacement of the ASLV envelope gene by an envelope gene from a virus capable of infecting both mammalian and avian cells. The resulting recombinant ASLV-derived retroviral vectors can replicate efficiently in avian cells, infect both avian and mammalian cells in high titer, and are replication-defective in mammalian cells. Thus, they are quite safe and advantageous for use in gene therapy and vaccines.

  • Patent number: 6492166
    Abstract: An Avian-derived retroviral vector from which the Constitutive Transport Element (CTE) has been removed and replaced with a genetic fragment from a mammalian virus in order to produce a vector that is replication competent in at least one non-native cell type without the need for a “helper” virus, and that is unlikely to recombine with endogenous mammalian viruses, making it both safe and simple to use in research and gene-therapy applications.

  • Patent number: 6218596
    Abstract: The present invention relates to DNA segments encoding chicken c-ski protein, to DNA constructs comprising the DNA segments and to cells transformed therewith. The present invention further relates to non-human transgenic mammals having increased muscle size and/or reduced fat. In addition, the present invention relates to methods of stimulating muscle growth and preventing degeneration of muscle, and to methods of treating muscle degenerative diseases and obesity.

  • Patent number: 6197499
    Abstract: The present invention relates to a method of detecting a DNA sequence by means of a DNA:DNA hybrid in real time using fluorescence. The present invention eliminates the need to use radioactive probes to detect the DNA and eliminates the delay needed for autoradiographic exposure of the X-ray to the radioactive label.

  • Patent number: 4997763
    Abstract: A stable, substantially nononcogenic vector having a cloning site for the convenient insertion of a gene of interest has been constructed by recombinant technology from an avian retrovirus. The construct is derived from Rous sarcoma virus and the cloning site is a replacement for the csr oncogene. This vector is useful for ferrying selected, expressible genes into avian germ cells for incorporation into the germ line. The vector is also useful for inserting and expressing foreign genes in somatic avian cells both in vivo and in vitro.
