General description

RealSeq® is a novel method for preparing small-RNA sequencing libraries that reduces incorporation bias in Next-Generation-Sequencing (NGS). Most bias stems from sequence-dependent variability in the enzymatic ligation reactions that attach the two adapters to the 3′ and 5′ ends of the miRNAs/small RNAs during preparation of sequencing libraries. By using a novel single adapter and circularization, RealSeq® greatly reduces library preparation bias. This technology solves the problem of commonly used sequencing library preparations that lead to underdetection of many miRNAs.

RealSeq®-AC is a small RNA library preparation kit compatible with Illumina Next Generation Sequencing (NGS) technology. RealSeq®-AC is optimized for RNA input between 1ng and 1000ng of total RNA from tissue or cells. This kit is for small RNA and miRNA library preparation for NGS. RealSeq-AC is highly efficient, detecting more miRNAs in total RNA samples.


RealSeq®-AC has been used for the construction of sRNA libraries from Rosa chinensis, Aquilegia coerulea, Triticum aestivum, and Hordeum vulgare.

Application Note
RealSeq® accurately quantifies small RNA sequenced on the Illumina Platform. RealSeq®-AC uses ligation of a single adapter producing small RNA libraries with more miRNAs compared to library prep kits using two adapters.

  • Significantly reduces sequencing bias in small-RNA sequencing
