Methodological study demonstrates single-molecule RNA in situ hybridization in routine tissue specimens, highlighting a viable platform for clinical molecular diagnostics.

Key Points

To introduce and evaluate RNAscope, a novel in situ hybridization technology designed to achieve sensitive and specific single-molecule RNA biomarker visualization within preserved tissue architecture.
Designed a specialized hybridization probe strategy that simultaneously amplifies target signals and suppresses background noise.
Assayed performance using standard formalin-fixed, paraffin-embedded clinical tissue specimens.
Implemented detection through conventional chromogenic dyes for bright-field microscopy alongside fluorescent dyes for multiplex expression analysis.
Achieved single-molecule visualization of individual RNA targets while fully preserving histological tissue morphology.
Demonstrated compatibility with routine formalin-fixed, paraffin-embedded tissues, bypassing the need for tissue-grinding extraction methods.
Enabled flexible target detection via both standard bright-field chromogenic assays and multiplexed fluorescent imaging.
