  • Publication number: 20230348888
    Abstract: This application relates to an aqueous mixture composition to collect, transport and store samples suspected of containing a pathogen, the composition comprising a chaotropic agent, a chelator, a detergent, a buffer, and optionally an alcohol. The composition inactivates pathogens and stabilizes nucleic acids and proteins contained within a sample and allows downstream extraction and detection assays to proceed without preprocessing. The composition further allows for sample pooling to facilitate high-throughput detection assays.

  • Patent number: 6503704
    Abstract: The present invention is directed to a method of determining the genotype of a human papilomavirus in a sample by amplifying a portion of the L1 open reading frame of human papilomavirus genome with the amplification primer having SEQ ID NO:2, the sequencing primer having SEQ ID NO:3 and an additional sequencing primer specific to HPV51 having SEQ ID NO:5.
    Type: Grant

  • Patent number: 6228577
    Abstract: This sequence of human papillomavirus present in a sample is determined by amplifying a portion of the L1 open reading frame of human papillomavirus genome to form L1 amplicons containing plus and minus amplified strands using MY09 and MY11 amplification primers, and then determining the positions of at least the A bases in the antisense amplicon using a consensus sequencing primer which is shifted six bases with respect to the MY09 primer (MY09-6). This primer has the sequence ARRGGAWACT GATCWARDTC (Seq. ID No. 3).
    Type: Grant
