  • Patent number: 7642057
    Abstract: A novel method for detecting chromosome aberrations is disclosed. More specifically, chromosome aberrations are detected by in situ hybridisation using at least two sets of hybridisation probes, at least one set comprising one or more peptide nucleic acid probes capable of hybridising to specific nucleic acid sequences related to a potential aberration in a chromosome, and at least one set comprising two or more peptide nucleic acid probes capable of hybridising to specific nucleic acid sequences related to another potential aberration in a chromosome. In particular, the method may be used for detecting chromosome aberrations in the form of breakpoints.

  • Publication number: 20030138353
    Abstract: A cartridge device for processing a sample mounted on a surface of or entrapped within the matrix of a support member and comprising a housing having a cavity therein and an aperture providing access for the introduction of said support member into said cavity so as to define two compartments when said support member is inserted therein, one of which compartments (called the first one) being defined by the sample bearing surface of the support member, an inner surface of the cavity and spacing means therebetween of such size, form and configuration that the dimension of said first compartment perpendicular to the sample bearing surface of the support member and the said inner surface of the cavity is of capillary dimensions, the other one compartment (called the second compartment) being defined by opposite surface(s) to the sample bearing surface of the support member and the remaining inner surface(s) of the said cavity, there being provided within said cavity elastically means engaging said support member

  • Patent number: 5888733
    Abstract: Methodologies for determining the presence of specific nucleic acid sequences in a sample of eucaryotic origin using in situ hybridization are described. The in situ hybridization is performed using a hybridization solution comprising at least one binding partner capable of hybridizing to the specific nucleic acid sequence to be determined so as to form hybrids and a hybrid destabilizing agent in an amount effective to decrease the melting temperature of hybrids formed between the nucleic acid and the binding partner so as to increase the specific binding and decrease the non-specific binding. The binding partner used is a polymeric strand of polymerized moieties having a non-cyclic backbone, the polymeric strand being capable of hybridizing to the nucleic acid sequence to be determined. The method is particularly suitable for diagnosing different human diseases such as bacterial and viral infections, genetic diseases and neoplastic disorders.

  • Patent number: 5612458
    Abstract: This invention relates to antibodies to complexes formed between PNA (Peptide Nucleic Acid) and nucleic acids, particularly antibodies to PNA/DNA or PNA/RNA complexes. The preferred antibodies are polyclonal, monoclonal and recombinant antibodies that binds to PNA/DNA or PNA/RNA complexes, but not to single-stranded PNA, double-stranded nucleic acid or single-stranded nucleic acid. Peptide Nucleic Acids (PNA) are newly developed, not naturally occurring compounds comprising a polyamide backbone bearing a plurality of ligands such as naturally occuring nucleobases attached to a polyamide backbone through a suitable linker. PNA oligomers with a backbone of N-(2-aminoethyl)glycin units have a surprising high affinity for complementary nucleic acid forming very stable and specific complexes. This property makes PNA oligomers suitable as hybridization probes for detection of nucleic acids. The usability of PNA as hybridization probes is greatly increased by the present antibodies.
