Adhere towards the newer recommendations). Molecular aberrations that interfere with miRNA processing, export, and/or maturation have an effect on mature miRNA levels and biological activity. Accordingly, most miRNA detection procedures focus on the analysis of mature miRNA as it most closely correlates with miRNA activity, is far more long-lived, and more resistant to nuclease degradation than a major miRNA transcript, a pre-miRNA hairpin, or mRNAs. Even though the quick length of mature miRNA presents benefits as a robust bioanalyte, in addition, it presents challenges for certain and sensitive detection.

Molecular aberrations that interfere with miRNA processing, export, and/or maturation affect mature miRNA levels and biological activity. Accordingly, most miRNA detection techniques focus around the evaluation of mature miRNA since it most closely correlates with miRNA activity, is far more long-lived, and much more resistant to nuclease degradation than a main miRNA transcript, a pre-miRNA hairpin, or mRNAs.
