The assay, which can be performed manually or automatically, can enable visualization of splice variants, short sequences, and mutations within the tissue context. Medicine RNAscope for In situ Detection of Transcriptionally Active Human Papillomavirus in Head and Neck Squamous Cell Carcinoma Hongwei Wang1, Mindy Xiao-Ming Wang1, Nan Su1, Li-chong Wang1, Xingyong Wu1, Son Bui1, Allissa Nielsen1, Hong-Thuy Vo1, Nina Nguyen1, Yuling Luo1, Xiao-Jun Ma1 1Advanced Cell Diagnostics, Inc. The presence of high-risk HPV in head and neck tumor tissue is associated with favorable outcomes. The recently developed RNA in situ hybridization technique called RNAscope allows direct visualization of HPV E6/E7 mRNA in FFPE tissue sections.
