Gel-Free Small RNA Library Prep with Reduced Bias

The NEXTFLEX® Small RNA-Seq Kit v4 uses patent-pending technology to provide a completely gel-free small RNA library preparation solution for Illumina® sequencing platforms. Our approach to reducing bias involves optimization of the ligation reaction and the use of dimer reduction oligonucleotides. These changes results in decreased bias in comparison to NEXTFLEX® Small RNA-Seq Kit v3 and standard protocols.

The legacy NEXTFLEX Small RNA-seq kits v3 are still available and can be found here.

NEXTFLEX® Small RNA-Seq Kit v4 allows preparation of libraries ready for sequencing with a simplified workflow in approximately 5 hours, with as little input as 1 ng of total RNA. Libraries prepared with this kit have a higher proportion of mapping reads and unique miRNAs than leading competitors (Figure 1 and 2).

Gel-free Library Prep with miRNA Isolated From Exosomes

This convenient gel-free workflow incorporated in the NEXTFLEX® Small RNA-Seq Kit v4 enables the construction of libraries from exoRNA. Using this workflow, researchers can achieve a high number of reads aligning to mature miRNA and low adapter dimers, even with the very low miRNA inputs characteristic of exosome samples.

Maximize miRNA Mapped Reads with NEXTFLEX® Blood miRNA Blockers

The NEXTFLEX® Blood miRNA blockers deplete common miRNA in blood and plasma such as miR-486-5p, miR-92a-3p and miR-451a. These constitute 50-70% of the small RNA present in those samples and usually are not of interest for researchers.

Small RNA-Seq Library Prep Optimized for Automation

By eliminating all gel-based steps even for low input samples, the NEXTFLEX® Small RNA-Seq Kit V4 is optimized for easy migration onto automated liquid handling platforms. This workflow is automated on the Sciclone® G3 NGSx, Sciclone G3 NGSx iQ™, and the Zephyr® G3 NGS workstations.

Illumina® Small RNA-Seq Multiplexing with UDI Barcodes

Up to 384 UDI barcoded primers are included in each kit for multiplexing. These UDIs were redesigned, allowing libraries prepared with this kit to be run on any Illumina® sequencing platform. These include the Illumina® NextSeq® and Novaseq® sequencers and only require standard Illumina® sequencing primers.
