    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 tested with the NEXTFLEX® Rapid Directional RNA-Seq Kit 2.0.

  • 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). Revvity’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.

    For total RNA-Seq solution not limited to only mRNA-Seq, Revvity offers the NEXTFLEX RiboNaut rRNA depletion kit (Human / Mouse / Rat) for use NEXTFLEX Rapid Directional RNA-Seq Kit 2.0 or other applications.
