Visualizing Genetic Variants, Short Targets, and Point Mutations in the Morphological Tissue Context with an RNA In Situ Hybridization Assay

Here, we describe an in situ hybridization assay which enables sensitive and specific detection of sequences as short as 50 nucleotides with single-nucleotide resolution at the single-cell level. The assay, which can be performed manually or automatically, can enable visualization of splice variants, short sequences, and mutations within the tissue context.
