RealSeq-AC small RNA library kit

The RealSeq®-AC kit from Somagenics offers a proprietary method for the preparation of small RNA sequencing libraries for Illumina® sequencers,  that minimises bias related to intramolecular RNA folding and adapter dimers. By using an efficient, gel-free approach, this technology detects more miRNAs in total RNA than other miRNA library preparation kits and is optimised for inputs between 1 ng - 100 ng total RNA.

Benefits of using the RealSeq-AC small RNA library kit  
• Eliminates bias-induced over/under-represented small RNAs
• Accurately quantifies biologically relevant small RNAs
• Optimised for inputs between 1 ng - 100 ng total RNA

RealSeq-AC technology detects more miRNAs in total RNA* than other miRNA library preparation kit
  Kit I Kit N Kit B Kit T RealSeq-AC
miRNAs with > 5 reads 404 452 412 324 500
miRNAs with > 10 reads 328 365 352 239 385

RealSeq-AC detects more miRNAs with over five or ten reads per million, respectively, from total RNA samples compared to other kits for miRNA sequencing library preparation.

Bias measurements comparing small RNA library preparation kits

Bias measurements comparing small RNA library preparation kits. 1 pmol of miRXPlore Universal Reference pool (Miltenyi Biotec) was used to compare incorporation bias in six different library preparation kits. Purified libraries were sequenced on the Illumina MiSeq platform. Trimmed sequencing reads were aligned to a custom miRNA reference. Reads mapping to miRNAs were counted and fold-deviations from the equimolar input were calculated and plotted as log2 values. Measurements of miRNA levels within a factor of two of the expected values (between vertical lines) are considered unbiased. The method of adapter attachment to the miRNAs is noted in the legend. Libraries prepared using RealSeq®-AC have substantially fewer miRNAs with bias than those prepared using any of five other commercially available library preparation kits.
