Adhere to the newer recommendations). Molecular aberrations that interfere with miRNA processing, export, and/or maturation influence mature miRNA levels and biological activity. Accordingly, most miRNA detection methods focus on the evaluation of mature miRNA because it most closely correlates with miRNA activity, is far more long-lived, and much more MedChemExpress GR79236 resistant to nuclease degradation than a principal miRNA transcript, a pre-miRNA hairpin, or mRNAs. Although the short length of mature miRNA presents benefits as a robust bioanalyte, in addition, it presents challenges for certain and sensitive detection.
