ViewRNA ISH probe set types
Probe sets are required for ViewRNA Assays and must be purchased separately. Each probe set type is specific to the detection label and brightfield/fluorescence readout. For multiplexing experiments, it is critical to avoid using more than one of the same probe set type per sample. Use the following table to determine which probe set type is needed for your experiment.

Select ViewRNA cell assay controls
Positive controls: For ViewRNA Cell Assays, housekeeping genes such as ACTB, GAPD, PPIB or UBC probe sets are commonly used as positive controls. For micro-RNA experiments, probe set for Let7a works for many samples.
Negative controls: Negative controls should be used in every experiment to help ensure proper evaluation of specific versus non-specific binding. Samples with the target specific probe omitted or samples labeled with a probe against a target not expressed in cells of interest are highly recommended.
Search probes used for positive and negative controls in probe search tool for the species. Please note that ViewRNA probes are very specific, and a probe set for one species commonly does not detect targets in another species.

Figure 1. Identification of breast cancer CTCs from human bone marrow using the ViewRNA ISH Cell Assay. A putative breast cancer tumor cell from a bone marrow sample was fixed and analyzed using the ViewRNA ISH Cell Assay for ERBB2 (green), pan-keratin panel (cytokeratin 8, 18, and 19) (yellow), and BACT (purple). The technology was used to identify the only two such CTCs on the slide. Data courtesy of Radium Hospital, Oslo, Norway.

SKBR3
Figure 2. Visualization and quantitation of transcript heterogeneity in cell lines using the ViewRNA ISH Cell Assay. Multiplex analysis of Her2 mRNA (green) and control 18S rRNA (red) in HeLa cells and SKBR3 cells. Nuclei were stained with DAPI (blue) and visualized by fluorescence microscopy.
Figure 3. Time course of gene expression after cytokine induction, at the single-cell level using the ViewRNA ISH Cell Assay. HeLa cells were treated with PMA for 0–8 hours. Then the cells were fixed and analyzed using the ViewRNA ISH Cell Assay for induction of IL-6 (red) and IL-8 expression (green). Nuclei were stained with DAPI (blue). The results show post-induction peaks at 1–2 hours for IL-6 and 4 hours for IL-8. Furthermore, the assay reveals the heterogeneity of individual cell responses.
Figure 4. Detection of H1N1 Influenza A RNA migration in cells using the ViewRNA ISH Cell Assay. Nuclear translocation of viral RNA is necessary for replication of the influenza virus. Murine embryonic fibroblasts (MEFs) were incubated on ice with influenza A virus (H1N1, PR8 strain). At time 0, virus was removed and medium (warmed to 37°C) was added. At the indicated time points after warming, the cells were fixed and processed using the ViewRNA ISH Cell Assay Kit with a probe set against the nucleoprotein (NP) viral genomic segment (green). Nuclei are stained blue with DAPI. Time dependent nuclear translocation of the NP genome is seen at 90 min post-infection, and by 180 min the export of newly synthesized viral genomes from the nuclei to the cytosol is also observed.

Figure 5. Multiplexing of viral RNA and mRNA in Huh7 cells. Multiplex fluorescence in situ detection of HCV genomic viral RNA (green) and 18S rRNA (red) in Huh7 cells lacking (–HCV) or containing (+HCV) a hepatitis C virus (HCV) replicon. Nuclei are stained with DAPI (blue).
Figure 6. Multiplex analysis of miRNA and mRNA of various expression levels using the ViewRNA Cell Assay. Simultaneous detection of miRNA (Fast Red substrate, Cy3/550 channel) and mRNA (in FITC channel or in Cy7 channel) expression in any given cell. Shown are duplex assays showing expression of different miRNA and mRNA targets in HeLa cells. HPRT, ACTB, and PPIB were detected in the FITC channel, and GAPD was detected in the Cy7 channel. Based on known expression levels, the data confirm accurate and precise study and visualization of miRNA and mRNA of various expression levels, where one distinct spot corresponds to one molecule of an miRNA or mRNA target.
Compound dose-response profiling
Figure 7. Visualization and quantitation of induction in cultured cells using the ViewRNA Cell Assay for high-content screening. HeLa cells were cultured in a 384-well clear bottom plate and treated with various concentrations of PMA. Following a 4-hour PMA treatment, cells were fixed and analyzed for IL-8 expression (green). Nuclei were stained with DAPI (blue).
Compound screening with multiple markers
Figure 8. Multiplex analysis of compound screens using the ViewRNA Cell Assay for high-content screening. Individual images show nuclei and RNA targets: gene 1, gene 2, and gene 3. The merged image shows simultaneous detection of the three RNA targets. Nuclei were stained with DAPI (blue). Data courtesy of Dr. Dan Garza, Proteostasis, Inc.
