  • Title: A general primer pair for amplification and detection of genital human papillomavirus types.
    Author: Evander M, Wadell G.
    Journal: J Virol Methods; 1991; 31(2-3):239-50. PubMed ID: 1650785.
    Abstract:
    A general primer pair localized in the E7 and E1 regions was identified and used for the detection of genital human papillomaviruses (HPVs). The genital HPV types 6b, 11, 16, 18, 31 and 33 were amplified and detected by the polymerase chain reaction (PCR) performed at a high stringency annealing temperature (60 degrees C). HPV-2, -3, -7, -13 and -30 were amplified only at lower temperatures. Twelve biopsies from women with invasive cancer in the cervix were analysed with the general primer pair. The amplification product specific for the general primer pair was detected in 11 of the 12 biopsies. The eleven HPV DNA positive specimens were shown to contain HPV-6b, HPV-16 and/or HPV-18 by Southern blot hybridization of the PCR products. The general primers were also used for analysis of 57 cervical scrapes from women with normal cytology, condyloma or CIN. By ethidium bromide staining after agarose gel electrophoresis we could detect 21 positives. Slot-blot analysis of the amplification products from all 57 scrapes confirmed the specificity of the 21 positives and revealed 5 additional positives. Among the 57 scrapes, 15/21 CIN scrapes, 10/21 condyloma scrapes and 1/15 normal scrapes contained HPV DNA. Eight different HPV types were detected. The general primer pair from the E7/E1 region is thus a powerful tool for the detection of HPV in clinical samples. The amplimer obtained offers a possibility for further typing by slot-blot hybridization using HPV-type specific probes.
