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