In Situ Hybridization (ISH) is a powerful technique that allows for specific localization of nucleic acid targets in fixed tissues, cells and circulating tumor cells (CTCs). The principle of ISH is that nucleic acids, when preserved adequately in a histologic specimen and when fixed appropriately, can be detected by using a nucleic acid probe, allowing you to obtain gene expression information in the context of tissue/cell morphology. In the past, quantitation of in situ gene expression, at the RNA (mRNAs or non-coding RNAs) level, had limited utility due to low sensitivity (e.g. non-radioactive formats), long complicated workflows (e.g. radioactive formats) and/or the inability to simultaneously multiplex.
ViewRNA Assays are novel RNA in situ hybridization (ISH) assays enabling localization and visualization of RNA in cells or tissues in singleplex and multiplex assay formats. ViewRNA Assays offer sensitive single-molecule RNA detection with virtually no background.
We offer two basic ways to visualize your RNA targets in situ: chromogenic (CISH) and fluorescence (FISH) detection.
