Study Purpose
The purpose of this study was to compare PCR amplification of the human papillomavirus (HPV) E6 gene and beta-globin gene fragments among DNA extracted from FFPE biopsy and autopsy specimens stored as paraffin blocks at ambient temperature from less than a year to 40 years.
Summary of Findings:
PCR amplification of beta-globin and HPV E6 gene fragments was successful using DNA extracted from FFPE specimens procured at biopsy or autopsy within a year of analysis. PCR amplification of a beta-globin fragment was successful for all archival specimens analyzed, although amplicon abundance displayed significant variability. Amplification of HPV E6 gene fragments was successful in 40% of archived specimens examined.
