Why use RNAscope ISH?
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, a Bio-Techne brand and 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.
