miRNA Assays

Discover miRNA biomarkers faster and more reproducibly with highly multiplexed, direct digital detection and quantification in a single assay.  nCounter miRNA Assays include off-the-shelf miRNA Panels for expression analysis of hundreds of miRNAs from human, mouse and rat samples and miRGE Assays for simultaneous measurement of user-defined miRNA and mRNA targets within the same sample.

nCounter miRNA Assays are compatible with a variety of sample types including FFPE, cell lysates, exosomes and biofluids and can be used for different areas of research such as cell signaling and cancer biology, neuroscience, stem cell research, autophagy, infectious disease, and immunology.
