RNAscope Assays
Four flexible solutions for all your research needs
Independent of your genes of interest, our easy RNA in situ hybridization assay uses common reagents and protocols; providing universal assay conditions. All RNA-ISH kits contain reagents in a convenient ready-to-use (RTU) format, and chromogenic dyes are available to interrogate a single or two genes simultaneously. Most versatile are our RNAscope® Multiplex Fluorescent Reagent Kits, enabling you to interrogate 1, 2 or 3 genes simultaneously.
Automated RNAscope® ISH assays are also available for Leica Systems (LS) and Ventana Systems (VS).
