Detection of HPV E6/E7 mRNA in Clinical Samples Using RNA In Situ Hybridization

: Detection of human papilloma virus (HPV) in tissue specimens has been a clinical challenge since last 2 decades; however, screening for presence of E6/E7 transcripts is regarded as the gold standard, and it verifies the active HPV infection. Here, we describe "RNAscope® assay" a novel RNA in situ hybridization (ISH) technology; which detects E6/E7 mRNA of seven high risk HPV subtypes (HPV 16, 18, 31, 33, 35, 52, and 58) in formalin fixed paraffin embedded (FFPE) tissue samples.
