MicroRNAs (miRNAs) are non-coding small RNAs that have cell type and cell context-dependent expression and function. To study miRNAs at single-cell resolution, we have developed a novel microfluidic approach, where flow fluorescent in situ hybridization (flow-FISH) using locked-nucleic acid probes is combined with rolling circle amplification to detect the presence and localization of miRNA. Furthermore, our flow cytometry approach allows analysis of gene-products potentially targeted by miRNA together with the miRNA in the same cells. We demonstrate simultaneous measurement of miR155 and CD69 in 12-O-tetradecanoylphorbol 13-acetate (PMA) and Ionomycin stimulated Jurkat cells. The flow-FISH method can be completed in ,10 h, utilizes only 170 nL of reagent per experimental condition, and is the first to directly detect miRNA in single cells using flow cytometry.
