  • Detection of human papillomavirus by the polymerase chain reaction
    Patent number: 5639871
    Abstract: The presence of human papillomavirus (HPV) in a sample can be detected and the HPV typed by a method that involves the amplification of HPV DNA sequences by the polymerase chain reaction (PCR). The primers used in the method are consensus primers that can be used to amplify a particular region of the genome of any HPV. The presence of HPV in a sample is indicated by the formation of amplified DNA. The HPV nucleic acid is detected by consensus probes that may be short oligonucleotide probes or long generic probes. The HPV is typed by the use of type-specific DNA probes specific for the amplified region of DNA.
    Type: Grant
    Filed: June 1, 1995
    Date of Patent: June 17, 1997
    Assignee: Roche Molecular Systems, Inc.
