  • Patent number: 6063913
    Abstract: A modified DNA sequence encoding full length cystic fibrosis transmembrane conductance regulator protein is provided to facilitate propagation and/or expression of the protein in living cells and in particular, bacterial cells. The modified DNA sequence comprises at least one of the 13 base pair repeat of exon 6b of the normal gene encoding the conductance regulator protein, as one or more normal nucleotides of the 13 base repeat substituted with an alternate nucleotide which, however, continues to code for the corresponding normal amino acid. Mammalian cells transfected with a vector containing the modified DNA sequence enhances chlorine conductance through the cell wall.

    Date of Patent: May 16, 2000
    Assignee: HSC Research and Development Limited Partnership
    Inventors: Lap-Chee Tsui, Johanna M. Rommens
  • Patent number: 6020126
    Abstract: A rapid and sensitive detection method capable of reliably distinguishing fragments identical to a defined sequence from fragments containing a single base pair mismatch relative to the defined sequence. The method employs a peptide analog antisense probe, such as a peptide nucleic acid (PNA) probe, which hybridizes with DNA to forms complexes having higher thermal stability, but greater sensitivity to base pair mismatches, than corresponding DNA/DNA complexes. The method may be used in a number of applications, including genetic screening and hybridization sequencing applications.

  • Patent number: 6001588
    Abstract: The identification, isolation and cloning of DNA sequences coding for mutant forms of the cystic fibrosis gene and their gene product are described. DNA sequence information and information relating to the genomic structure of the cystic fibrosis gene are provided. The mutant forms of the CF gene include specific sequence alterations in coding portions or of other genetic information at exon/intron boundaries and altered RNA transcripts and mutant protein products. Such DNA and protein information is useful in developing DNA or protein diagnosis for CF mutations, carrier and patient screening, as well as cloning of mutant genes and manufacturing of their proteins for investigation into therapies for cystic fibrosis.

  • Patent number: 5470709
    Abstract: A method is provided for detecting, ordering and mapping genes or DNA sequences in the genome of eukaryotic cells. The method comprises the steps of releasing free chromatin from the nuclei of the cells and contacting the released free chromatin with at least one detectable probe capable of hybridizing to the genes or DNA sequences to be detected, thereby rendering the genes or DNA sequences detectable.
