A unique system developed specifically for miRNA profiling
The miRCURY LNA miRNA PCR System offers the best available combination of performance and ease-of-use on the market, because it unites two important features (see figure Schematic outline of the miRCURY LNA miRNA PCR System):
  • One cDNA reaction for all miRNAs – One single universal first-strand cDNA synthesis reaction is used as the template, regardless of the number of miRNAs being profiled. This saves precious sample, reduces technical variation, reduces pipetting and saves time in the laboratory.
  • Two LNA-enhanced miRNA qPCR primers – Both qPCR primers are miRNA-specific and optimized with LNA. LNA primers bind with high affinity and are shorter than standard PCR primers, so both primers can fit on the miRNA without overlapping. The result is unrivalled sensitivity and specificity and extremely low background.

Unmatched sensitivity
Universal RT combined with LNA-enhanced and Tm normalized primers enables accurate and reliable quantification of individual miRNAs, from as little as 1 pg total RNA (see figure Accurate quantitation from down to 1 pg total RNA starting material). In comparison to other miRNA real-time PCR systems that use either stem-loop or standard DNA primers, the LNA-enhanced primers offer significantly increased sensitivity, especially for AU-rich miRNAs.

Exceptional sensitivity and extremely low background enable accurate quantification of very low levels of miRNA without the need for pre-amplification. This makes the miRCURY LNA miRNA PCR System suitable for all sample types, and especially samples with low RNA content, such as biofluids like serum and plasma.

Fully validated and optimized
All miRCURY LNA RT miRNA PCR primer sets have been optimized for maximum sensitivity and thoroughly validated either by wet-lab testing or in silico. In wet-lab validation, over 95% of assays detect 10 miRNA copies or less in the PCR reaction (see figure Serial dilution of hsa-miR-181a). The primer sets have also been validated for specific amplification of the target and for minimal background signal.

Truly specific – no false positives
The incorporation of LNA in the qPCR primers facilitates the design of assays that can distinguish between miRNA sequences that differ by a single nucleotide. This makes it a truly specific miRNA qPCR platform that gives no false-positive signals (see figure Specificity results from the miRQC Study). In addition, the assays can discriminate between mature miRNA sequences and precursor miRNA.

Fast, easy and reproducible
Save time and effort in the laboratory with the 3-hour, easy-to-follow protocol that minimizes pipetting. By using the same cDNA as the template for all subsequent PCR reactions, the procedure is greatly simplified compared to systems that require miRNA-specific cDNA synthesis. With fewer pipetting steps, technical variation is also reduced. As a result, it is possible to achieve extremely high reproducibility from day-to-day (see figure Excellent day-to-day reproducibility) and even site-to-site.
