Chapter 1. Product Information
1
Before using this product, read and understand the information in Appendix C. Safety on page 23 in this document. IMPORTANT! We recommend reading the entire user manual before beginning any protocols.
About this guide This user manual provides guidelines and protocols for the proper preparation and pretreatment of formalin-fixed, paraffin-embedded (FFPE) tissues mounted on slides. The slides can then be assayed using an RNAscope® Detection Kit. RNAscope® Reagent Kits come with a separate RNAscope® Assay User Manual. Do not perform an RNAscope® Assay without the correct user manual. Refer to the manuals available at www.acdbio.com/support/technical-doc for more details. For any questions, please contact [emailprotected].
Product description Background The RNAscope® Assays use a novel and proprietary method of in situ hybridization (ISH) to visualize single RNA molecules per cell in samples mounted on slides. The assays are based on ACD’s patented signal amplification and background suppression technology. Proprietary RNA-specific probes are hybridized to target RNA, and are then bound to a cascade of signal amplification molecules culminating in signal detection (Figure 1). Single-plex, 2-plex, multiplex and automated assays are all available. The RNAscope® Assay procedure is illustrated in Figure 1 on page 6 and can be completed in 6–10 hours depending on the assay, or conveniently divided over two days. Most RNAscope® Assay reagents are available in convenient Ready-To-Use (RTU) dropper bottles and provide a simple, nearly pipette-free workflow. Results are observable using standard bright field or fluorescent microscopy.
Sample types In order to perform the RNAscope® Assays, you must start with properly prepared and pretreated samples. Multiple sample types are now compatible with RNAscope® Assays and include: formalin-fixed paraffin-embedded (FFPE) tissues, fresh frozen tissues, fixed frozen tissues, tissue microarray (TMA), and cultured cells. Visit www.acdbio.com and contact [emailprotected] for more information.

2: Hybridize to target RNA
Start with properly prepared sections and pretreat to allow access to target RNA.
Hybridize gene-specific probe pairs to the target mRNA.
3: Amplify signal
4: Image
Probes are hybridized to a cascade of signal amplification molecules, culminating in binding of HRP- or AP-labeled probes. The 2.0 Assay enhances signal further with additional amplification steps. Add DAB or Fast Red substrate to detect target RNA.
Visualize target RNA using a standard bright field microscope.
RNAscope® Assay reagents RNAscope® Assays require the RNAscope® Probes and an RNAscope® Detection Kit. If you are performing an automated assay using the Ventana® DISCOVERY XT or ULTRA Systems, you must use RNAscope® VS Probes and the RNAscope® VS Reagent Kit. Probes and Reagent Kits are available separately. Visitwww.acdbio.com/products/target-probes/search-product to find a gene-specific probe from a searchable catalog of >27,000 predesigned Target Probes, or order a custom probe. Visit www.acdbio.com/products/target-probes/controls-housekeeping to find appropriate Control Probes.
RNAscope® Reagent Kit Each RNAscope® Detection Kit provides enough reagents to stain ~20 tissue sections approximately 20 mm x 20 mm large. Larger tissue sections will result in fewer tests. Each kit contains three sub-kits including a Pretreatment Kit (Cat. no. 310020). Pretreatment Kit instructions are provided in this guide. For information on the other sub-kits and directions for use, refer to an RNAscope® Detection Kit User Manual. The reagents have a shelf life of six months from the shipment date when stored as indicated in the following table: Pretreatment Kit (Cat. no. 310020) Reagent

Chapter 2. Before You Begin Prior to running the RNAscope® Assay on your samples for the first time, we recommend that you: • View the video demonstrations available at www.acdbio.com/support/online-trainingvideos. • Run the assay on FFPE RNAscope® Control Slides (Cat. no. 310045 for Human control slide, Hela; Catalog No. 310023 for Mouse control slide, 3T3) using the Positive and Negative Control Probes.
Important procedural guidelines • Start with properly fixed and prepared sections. Refer to Chapter 3. Prepare and Pretreat Samples on page 11 for preparation of FFPE slides. For preparation of other sample types, contact [emailprotected]. • Follow the recommended pretreatment guidelines for your sample. Refer to Appendix A. Tissue Pretreatment Recommendations on page 19 for pretreatment conditions. • Always run positive and negative control probes on your sample to assess sample RNA quality and optimal permeabilization. • Do not substitute required materials.

Tissue
Slide Label
IMPORTANT! Do not let the barrier touch the section.
Note: We do not recommend drawing a smaller barrier and using less than the recommended volume amounts, even for smaller sections. Larger barriers will result in fewer tests per kit. 2.
Let the barrier DRY completely ~ 2 MINUTES or OVERNIGHT at Room Temperature. Note: If you need to reapply the hydrophobic barrier during the following procedures, dry the appropriate area of the slide with a kimwipe. Do not touch the tissue section.
