MicroRNAs are small non-coding RNA molecules with length of about 22 nt. These molecules participate on regulation of gene expression at the post-transcriptional level. They represent the largest group of regulators in the cell and therefore are also involved in all key processes such as proliferation, differentiation or apoptosis. Moreover, they participate in tumor transformation. These small molecules have a great potential to be diagnostic markers or assist in the treatment and prevention of diseases. This research was focused on the development of isolation method using magnetic particles with subsequent electrochemical detection of microRNA. Optimization steps were performed and then the entire method was successfully applied to real samples of HEK293 cells expressing increased levels of miR-124. The developed method proved to be sufficiently specific and applicable to the analysis of microRNA.
