Description

The NEXTFLEX® Poly(A) Beads 2.0 kit offers a convenient method for the purification of pure, intact mRNA upstream of RNA-Seq library prep with improved mRNA yields, low rRNA contamination, and a simple protocol.

For research use only. Not for use in diagnostic procedures. 
  • 10 ng – 5 µg total starting RNA
  • Magnetic bead-based protocol
  • No organic solvents or precipitation step required
  • Tested using the NEXTFLEX® Rapid Directional RNA-Seq Kit 2.0
  • Optimized for use with 10 ng – 5 µg of total RNA as starting material
  • Automated on the Sciclone® G3 NGSx and Zephyr® G3 NGS workstations

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.

  • 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.
