Why use RNAscope ISH?

Bio- Techne offers 3 unique assays to detect RNA in the tissue context at single-molecule sensitivity with single-cell resolution: RNAscope for mRNA or ncRNA greater than 300 nucleotides in length, BaseScope for exon junctions, splice variants, and highly homologous or short sequences and assay miRNAscope  that enables detection of small non-coding RNAs such as miRNAs,  or other smaller sequences from 17-50nts as well as small therapeutic oligos such as ASOs or siRNAs

  • RNA is ideal biomarker
  • Detect mRNA for targets with no or poor antibodies
  • Validates High-throughput transcriptomic results
  • Complements qPCR results
  • Complements IHC data
  • Compatible for virtually any species, gene or tissue type
