Abstract [en]

Here we describe a method for sensitive and specific histological detection of microRNAs (miRNAs) by in situ hybridization. The protocol focuses on the use of locked nucleic acids (LNAs), which are bi-cyclic RNA analogs that allow a significant increase in the hybridization temperature and thereby an enhanced stringency for short probes as required for miRNA detection. The protocol is optimized for cryosections in order to study the spatial and temporal expression of miRNAs with high sensitivity and resolution. We detail how to construct probes, set up and conduct an LNA in situ hybridization experiment. In addition, we discuss alternative colorimetric strategies that can be used to effectively detect and visualize miRNAs including double staining with other markers. Setting up and conducting the in situ experiment is estimated to take similar to 1 week, assuming that all the component parts are readily available.
