  • Title: Visualization of individual microRNA molecules in fixed cells and tissues using target-primed padlock probe assay.
    Author: Lin C, Jiang M, Duan S, Qiu J, Hong Y, Wang X, Chen X, Ke R.
    Journal: Biochem Biophys Res Commun; 2020 Jun 04; 526(3):607-611. PubMed ID: 32247612.
    Abstract:
    MicroRNAs (miRNAs) are key regulators of gene expression at the posttranscriptional level. Precisely profiling of miRNA expression will help us to better understand their roles in normal and diseased cells and tissues. Here we describe in situ miRNA detection by padlock probing and miRNA target-primed rolling circle amplification. We optimized our protocol and showed it can be applied to both fixed cells and tissue sections. The method can be used in basic research and potentially in clinical diagnostics in the future.
