Adhere to the newer guidelines). Molecular aberrations that interfere with miRNA processing, export, and/or maturation impact mature miRNA levels and biological activity. Accordingly, most miRNA detection solutions focus around the analysis of mature miRNA since it most closely correlates with miRNA activity, is much more long-lived, and much more resistant to nuclease degradation than a key miRNA transcript, a pre-miRNA hairpin, or mRNAs. Though the short length of mature miRNA presents positive aspects as a robust bioanalyte, additionally, it presents challenges for specific 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 approaches focus on the analysis of mature miRNA because 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. Though the quick length of mature miRNA presents positive aspects as a robust bioanalyte, it also presents challenges for specific and sensitive detection.
