NEXTFLEX® Poly(A) Beads 2.0
The kit offers a convenient method for the purification of pure, intact mRNA upstream of RNA-Seq library prep. Poly(A)-tailed mRNA is isolated via magnetic beads conjugated to oligo(dT), and separation using a magnetic stand allows for high mRNA recovery. The intact mRNA is eluted in small volumes, thereby eliminating the need for precipitation. These beads have been validated with the new and improved NEXTFLEX® Rapid Directional RNA-Seq Kit 2.0.

NEXTFLEX® Poly(A) Beads 2.0 for Reducing Ribosomal rRNA Reads in RNA-seq Libraries
Several approaches have been used to remove ribosomal RNA (rRNA) from total RNA samples for RNA-Seq library preparation. Removal of rRNA avoids the waste of reagents and bioinformatics resources to sequence and align ~85% of total RNA comprising rRNA (which is generally not a target of interest in NGS sequencing experiments). PerkinElmer’s NEXTFLEX® Poly(A) beads 2.0 kit offers an easy and cost-effective method for removing rRNA in RNA-Seq libraries. This product takes advantage of the tract of adenosine residues present at the 3’ends of a vast majority of protein-coding mRNAs. Hybridization of these poly(A) tails to tracts of complementary thymidines (“oligo dT”) immobilized on solid supports allows the retrieval of poly(A)+ RNAs by recovering the solid support along with the hybridized RNA complexes.
Figure 1.Example of 1 µg of Universal Human Reference RNA (Agilent® # 740000) after Poly(A) enrichment using the NEXTFLEX® Poly(A) Beads 2.0. 3 µL Poly(A) enriched RNA was run on the LabChip® GXII Touch™ HT instrument using the RNA Pico Assay Reagent Kit (# CLS960012) and a DNA/RNA/Charge Variant Assay LabChip (# 760435)
Figure 2. NEXTFLEX® Poly(A) Beads 2.0 yield clean mRNA with minimal rRNA carry-over from 5 µg of total RNA input from (A) mouse brain and (B) MCF7 cells. ~1.5% rRNA carry-over was observed based on sequencing data.
