Standard molecular methods for disease profiling rely on dissociated cells that results in a loss of spatial information. However, a more complete and contextual understanding of the molecular mechanisms underlying cellular behavior requires complementary information on the subcellular localization of events, something that is only possible by use of in situ hybridization.?The RNAscope assay, a novel multiplex nucleic acid ISH technology with a patented probe design, amplifies target-specific signals but not background noise, delivering clear and actionable results with high sensitivity and specificity.
Key RNAscope ISH Technology Applications
Advanced Cell Diagnostics,?leaders in the emerging field of spatial genomics and?spatial transcriptomics, offers a unique RNAscope in situ hybridization?assay, that enables visualization of?gene expression at a single cell level, within an intact tissue.?
RNAscope ISH Technology can be applied over many applications, learn more about key areas of focus, including neuroscience, cancer, immune-oncology, cell and gene therapy and single-cell analysis.?
Getting Started with RNAscope ISH Technology
Similar to solving a jigsaw puzzle, successfully performing the technique of in situ hybridization (ISH) benefits from a systematic, stepwise approach that concentrates on one stage of the process at a time, then moves onto the next. ACD’s RNAscope ISH Technology represents a huge advance in the power and ease of use of ISH, greatly simplifying and streamlining time-tested methods while routinely delivering single-molecule detection levels of sensitivity. While not as simple as doing a four-piece jigsaw puzzle, we have made ISH considerably easier than it was formerly.
RNAscope ISH Technology Manual Assays
Techniques for detection of RNA in situ (ISH and ISH) have been around for years, as have the perceived gold standards of microarrays and PCR. However, these techniques lack clinically relevant information regarding spatial expression in the cellular and tissue microenvironment.
Our scientists at Advanced Cell Diagnostics, revolutionized the RNA ISH method and in 2011 introduced RNAscope? ISH for spatial detection of target RNA within intact single cells. With its proprietary probe design, to simultaneously amplify target-specific signals and suppress background noise from non-specific hybridization, RNAscope ISH is now a proven technology that is available in both manual and automated formats.
RNAscope
The most widely used RNAscope Assay.
Available in both chromogenic and fluorescent labels.
May be used as single plex, duplex, fourplex, and HiPlex formats.
Robust, sensitive, and archivable results.
miRNAscope
Used to detect small non-coding RNAs including miRNAs, ASOs, and siRNAs.
Visualize gene regulation with spatial and morphological context.
Detection via single Plex and chromogenic Fast Red.
BaseScope
Detects exon junctions, splice variants, short/highly homologous RNA sequences, and point mutations.
Sensitive detection at single-nucleotide differences.
Available in single (red) or Duplex kits.
DNAscope
Detects and qualifies gene copy number (amplifications/detections) and gene rearrangements/fusions.
Hi-res and precise target detection for small genomic regions/single gene focus.
A chromogenic Duplex assay (red/blue) visualized using brightfield microscopy.
RNA-Protein Co-Detection Assay
Enables simultaneous detection of cell-type specific gene expression and secreted proteins.
Correlate RNA-Protein expression and visualize cell margin and RNA targets.
Acquire more data and conserve precious samples.
RNA ISH Technology Automated Assays
The RNAscope in situ Hybridization Technology has been developed for both manual and automated protocols. If you require high throughput or an automated solution, ACD has partnered with Leica Biosystems and Roche Tissue Diagnostics, to deliver RNAscope ISH automated assays.
Leica Biosystems Inc.
In this strategic partnership, we have developed an automated RNA ISH workflow for the Leica BOND Rx IHC ISH platform
Roche Tissue Diagnostics
We have developed an automated RNA ISH workflow solution for use with the Roche Ventana and Benchmark ISH & IHC Staining Platforms.
