miRVEL Profiling Small RNA-Seq Library Prep

The miRVEL Profiling Small RNA-Seq Library Prep Kit provides the ideal solution for sRNA profiling studies with unique dual indices (UDIs). The miRVEL Profiling technology effectively prevents the formation of adapter dimers through adapter blocking, eliminates purification steps prior to library amplification and the need for gel-based size selection for a fast and streamlined sRNA-Seq workflow.

Excellent reproducibility

miRVEL Profiling Small RNA-Seq Library Prep Kit generates data with a high correlation between replicates and different input amounts.

Performance

miRVEL Profiling Small RNA-Seq generates excellent gene count correlation between replicates at low read depth of 1 M reads / sample (Fig. 1A, 1B). High correlations are achieved even for low inputs of 10 ng total RNA from human brain (Fig. 1 B) and across a range of inputs highlighting the robustness of the miRVEL Profiling protocol (Fig. 1C).

C) Correlation between 100 ng and 10 ng input RNA amount. The libraries were sequenced on NovaSeq X and downsampled to at 1 M read / sample prior to the analysis emphasizing performance even at low sequencing depth.

miRVEL Profiling Small RNA-Seq exhibits robust mapping rates to miRNA for libraries generated from 10 ng or 100 ng of human brain RNA (Fig. 2).

Figure 2 | Percentage of reads mapping to miRNAs. Libraries were prepared in triplicates from 100 ng and 10 ng of human brain RNA using the miRVEL Profiling Small RNA-Seq Library Prep. The obtained libraries were sequenced on NovoSeq X and downsampled to 1 M read / sample.

miRVEL Profiling Small RNA-Seq demonstrates a high detection of miRNAs across different inputs of human brain RNA even at low sequencing depth of 1 M reads / sample (Fig. 3).

Figure 3 | Number of detected miRNAs. Libraries were prepared from 10 – 100 ng of human brain RNA with the miRVEL Profiling Small RNA-Seq Library Prep kit. The obtained libraries were sequenced on NovaSeq X and downsampled to 1 M read / sample prior to analysis. The number of detected miRNAs is plotted for mature miRNAs detected with ≥ 5 uniquely mapped reads.

Workflow

Step1:
Input RNA (total RNA, enriched small RNA) is first subjected to 3’ adapter ligation.
The Blocking Reagent (BR) effectively prevents the formation of adapter dimers.
5’ adapter is ligated to the 5′ end of input RNA.
The input RNA, flanked by 5’ and 3’ adapters, is converted into cDNA with the RT primer binding to the 3’ adapter.

Unique dual i7 and i5 indices are integrated during the PCR library amplification step.

The amplified libraries are subjected to clean-up and concentration step. Libraries are now ready for sequencing.
