  • Publication number: 20120308594

  • Patent number: 7196183
    Abstract: The present invention relates to genomic nucleotide sequences and amino acid sequences corresponding to the non-coding and coding region of a new type of HCV. The invention relates to new HCV types and subtypes sequences which are different from the known HCV types and subtypes sequences. Particularly, the present invention relates to said new HCV type sequences; a process for preparing them, and their use for diagnosis, prophylaxis and therapy. More particularly, the present invention provides new type-specific sequences of the 5? NCR, Core, the E1 and the NS5 regions of the new HCV type. These new HCV sequences are useful to diagnose the presence of HCV type genotypes or serotypes in a biological sample. Moreover, the availability of these new type-specific sequences can increase the overall sensitivity of HCV detection and should also prove to be useful for prophylactic and therapeutic purposes.

  • Publication number: 20070031828
    Abstract: A process for identification of type-specific polynucleotide sequences in a sample, the process comprising the steps of (1) contacting polynucleotides from the sample, or derived from the sample, with a plurality of type-specific probes in the context of a solid support, and detection of any type-specific hybridisation; and (2) contacting polynucleotides in the sample, or derived from the sample, with type-specific primers for those types capable of being detected by the hybridisation step in step 1, but not so detected, in a type-specific amplification reaction.

  • Publication number: 20030165821
    Abstract: A method for detection and/or identification of HPV present in a biological sample comprising amplification of HPV polynucleic acids and of hybridization of said amplified polynucleic acids to a number of probes whereby a short fragment of the L1 gene of HPV is amplified after which, the amplimers are contacted with probes that specifically hybridize to the said short fragment of the L1 gene of at least one HPV type and a diagnostic kit to perform said method and primers and probes used in the said method.

  • Patent number: 6482588
    Abstract: The present invention relates to a method for detection and/or identification of HPV present on a biological sample, comprising the steps of amplification of HPV polynucleic acids and of hybridization of said amplified ploynucleic acids to a number of probes. By means of PCR, a short fragment of the L1 gene of HPV is amplified. The amplimers are then contacted with probes that specifically hybridize to said short fragment of the L1 gene of either one or more than one HPV type. A preferred format is the reverse hybridization technique, more particularly the LiPA technique. The invention also relates to primers and probes to be used in a method of detection and/or identification of HPV and to a diagnostic kit to perform said method.
