Detection of human papilloma virus DNA sequences by polymerase chain reaction.

We have developed a polymerase chain reaction-based procedure for reproducible detection of the E6-E7 gene in human papilloma virus DNA sequences using formalin-fixed, paraffin-embedded tissue sections. This procedure is a simple one-step procedure which does not require any elaborate hybridization following polymerase chain reaction amplification. The protocol combines modified tissue treatment and proper primer selection for efficient amplification of target DNA in a highly specific manner allowing identification in ethidium bromide-stained gels. The procedure described here is useful for a variety of tissue preparations, particularly formalin-fixed, paraffin-embedded archival tissues.
