RNAscope® Fluorescent Multiplex Assays

Spatial analysis of gene expression is an essential tool for comprehensive studies of complex, highly heterogeneous tissues, such as the brain, tumors, and developing organs. Traditional RNA-ISH can be challenging due to low sensitivity, inconsistent detection accompanied with limited plexing. RNAscope® Fluorescent Multiplex assays provide exceptional sensitivity, allowing single-molecule detection of RNA targets at the single cell level. The RNAscope® Multiplex Fluorescent assays are ideal for simultaneous detection studies of any genes in nearly any tissue-type using fluorescent labels. We offer with various levels of plexing to:

  • FIND cells of interest by using cell specific markers
  • CONFIRM cells by simultaneous detection of additional targets
  • CHARACTERIZE cellular heterogeneity of complex tissues by mapping and identifying multiple cell subtypes simultaneously

 

“Adding a histological context to scRNAseq data is important for fully understanding the biology of distinct cell populations, and HiPlex RNAscope is a great way to do this. The ability to stain a single section of tissue with up to 12 mRNA probes makes HiPlex RNAscope a powerful tool for distinguishing cells types in situ. While the HiPlex RNAscope protocol is relatively straightforward to conduct, ACD Bio has always been there to help when I need sales or technical assistance. I would recommend HiPlex RNAscope to anyone looking to visualize distinct populations of cells from scRNAseq data in situ.”

RNAscope® In Situ Hybridization Assay Workflow

  • Step 1:

    Permeabilize

    Tissue sections or cells are fixed onto slides and pretreated with RNAscope® Pretreatment Kit to unmask target RNA and permeabilize cells.

  • Step 2:

    Hybridize

    Designed with ~20 target-specific double Z probes, RNAscope® Probes hybridize to target RNA molecules.

  • Step 3:

    Amplify

    RNAscope® Detection Reagents amplify the hybridization signals via sequential hybridization of amplifiers and label probes.

  • Step 4:

    Visualize

    Each punctate dot signal represents a single test target RNA molecule and can be visualized with a microscope.

  • Step 5:

    Quantify

    Single-molecule signals can be quantified on a cell-by-cell basis by manual counting or automated image analysis using HALO Software.
