Do you need increased sensitivity and specificity from your RNA-seq experiments? Do you have ever-decreasing amounts of input RNA? To address these challenges, our next generation of RNA library prep kits have been reformulated at each step, resulting in several fold higher yields of high quality libraries, enabling use of lower input amounts and fewer PCR cycles.

Our new NEBNext Ultra II RNA kits have streamlined, automatable workflows and are available for directional (strand-specific, using the "dUTP method") and non-directional library prep and are compatible with poly(A) mRNA enrichment or rRNA depletion. The kits are available with the option of SPRISelect® beads for size-selection and clean-up steps.

Why consider the NEBNext Ultra II Directional RNA Library Prep Kit?

  • Get more of what you need, with the highest library yields
  • Generate high-quality libraries even with limited amounts of RNA:
    • 10 ng – 1 µg Total RNA  (poly(A) mRNA workflow)
    • 5 ng – 1 µg Total RNA (rRNA depletion workflow)
  • Minimize bias, with fewer PCR cycles required
  • Increase the complexity and transcript coverage of your libraries
  • Maximize flexibility by ordering reagents for your specific workflow needs, including directional and non-directional kits, rRNA depletion and poly(A) mRNA isolation reagents, and adaptors and primers (12- and 96-index) sold separately
  • Enjoy the reliability of the gold standard SPRIselect size selection and clean-up beads, supplied in just the amounts you need
  • Save time with streamlined workflows, reduced hands-on time, and automation compatibility
  • Rely on robust performance, even with low quality RNA, including FFPE

Are you looking for non-directional library prep?

The Wellcome Trust Sanger Institute has recently re-evaluated its RNA-seq library preparation methods and has chosen to implement the NEBNext Ultra II Directional RNA Library Prep Kit. Our previous RNA-seq library preparation required a minimum input of 500 ng total RNA, but the high efficiency of the NEBNext Ultra II kit has allowed us to reduce this to either 100 ng for a standard pipeline, or down to just 5 ng for a low input option, enabling RNA-seq to be carried out from just 5,000-10,000 cells.
