NEBNext® rRNA Depletion Kit v2 (Human/Mouse/Rat) with RNA Sample Purification Beads

This product provides superior performance compared to the original E6350 kit.


Catalog #E7405

Product Introduction

The abundance of ribosomal RNAs (rRNAs), constituting 80–90% of total RNA, necessitates removal upstream of next generation sequencing and other applications. This second generation rRNA depletion kit incorporates reagent, probe and protocol improvements, resulting in superior depletion performance. The efficient RNAse-H-based workflow, and close spacing of probes, enables effective depletion from both low- and high-quality RNA, with a broad range of input amounts. 

For added convenience, this kit contains NEBNext RNA Sample Purification Beads (Agencourt® RNAClean® XP beads from Beckman Coulter).

  • Superior depletion of rRNA from human, mouse and rat RNA
  • Depletion of cytoplasmic (5S, 5.8S, 18S, 28S, human ITS, ETS) and mitochondrial (12S and 16S) rRNA
  • Compatible with a broad range of input amounts: 10 ng - 1 µg
  • Suitable for low-quality or high-quality RNA
  • Fast workflow: 2 hours, with less than 10 minutes hands-on time

The kit is also available without RNAClean® beads. 

Product Information

Description

Highly expressed transcripts with minimal biological interest, such as ribosomal RNA (rRNA) can dominate readouts, masking detection of more informative low-abundance transcripts. This second-generation NEBNext rRNA Depletion Kit is has been further optimized to incorporate reagent, probe and protocol improvements to the RNaseH-based workflow, resulting in superior depletion performance. 

  • The efficiency of this workflow, and close spacing of probes, enables effective depletion from both low- and high-quality RNA, with a broad range of input amounts from human, mouse and rat samples.
  • The rRNA-depleted RNA can be used in RNA-seq, random-primed cDNA synthesis, or other RNA analysis methods. 
  • The NEBNext® rRNA Depletion Kit v2 (Human/Mouse/Rat) depletes cytoplasmic (5S, 5.8S, 18S, 28S, human ITS, ETS) and mitochondrial (12S, 16S) rRNA.
  • The kit is also available without RNAClean® beads.     


Figure 1: The NEBNext rRNA Depletion Kit v2 enriches for RNAs of interest across a wide range of total RNA inputs in human, mouse and rat



Universal human, mouse and rat reference total RNA (1 µg, 100 ng and 10 ng) was depleted of rRNA using the NEBNext rRNA Depletion Kit v2 (Human/Mouse/Rat). RNA-seq libraries were prepared using NEBNext Ultra II Directional RNA Library Prep Kit for Illumina followed by paired-end sequencing (2 x 75 bp). 10 Million reads were sampled (seqtk) from each library and reads were identified as ribosomal using mirabait (6 or more shared 25-mers) with rRNA sequences for human baits (5S, 5.8S, 12S, 16S, 18S, 28S, ETS/ITS) or mouse/rat baits (5S, 5.8S, 12S, 16S, 18S, 28S). Levels of rRNA remaining were calculated by dividing matched reads by the total number of reads passing instrument quality filtering. The data represents an average of 3 replicates. The NEBNext rRNA Depletion Kit v2 is efficient at depleting rRNA across species and input amounts.




Figure 2: Treatment with the NEBNext rRNA Depletion Kit v2 does not affect the abundances of non-targeted transcripts



Universal human, mouse and rat reference total RNA (1 µg) was depleted of rRNA using the NEBNext rRNA Depletion Kit v2 (Human/Mouse/Rat). RNA-seq libraries were prepared from untreated and depleted RNA using the NEBNext Ultra II Directional RNA Library Prep Kit for Illumina followed by paired-end sequencing (2 x 75bp). 10 million reads were sampled (seqtk) for depleted libraries and 100 million reads for undepleted libraries. GENCODE v27 transcript abundances were estimated using Salmon. Read Counts and R2 values for the linear fit are shown. Transcript expression is consistent after depletion across species.




Figure 3: Transcript expression correlation is preserved across a wide range of inputs



Universal human, mouse and rat reference total RNA (1 µg) was depleted of rRNA using the NEBNext rRNA Depletion Kit v2 (Human/Mouse/Rat). RNA-seq libraries were prepared using the NEBNext Ultra II Directional RNA Library Prep Kit for Illumina followed by paired-end sequencing (2 x 75bp). GENCODE v27 transcript abundances were estimated using Salmon. Read Counts and R2 values for the linear fit are shown. Transcript expression correlation is consistent regardless of input amount.




Figure 4: The NEBNext rRNA Depletion Kit v2 efficiently depletes rRNA from degraded FFPE total RNA while preserving transcript abundances



Human adult normal liver tissue FFPE Total RNA, RIN 2.3 (100 ng and 10 ng) was depleted of rRNA using the NEBNext rRNA Depletion Kit v2 (Human/Mouse/Rat) (A, B, C) or the TruSeq® Stranded Total RNA Gold kit (A). RNA-seq libraries were prepared using the NEBNext Ultra II Directional RNA Library Prep Kit for Illumina® followed by paired-end sequencing (2 x 75 bp). 20 Million reads were sampled (seqtk) from depleted libraries and 200 million reads from undepleted libraries. (A) Reads were identified as ribosomal using mirabait (6 or more shared 25-mers) with rRNA sequences for 5S, 5.8S, 12S, 16S, 18S, 28S and ETS/ITS as baits. Levels of rRNA remaining were calculated by dividing matched reads by the total number of reads passing instrument quality filtering. The data represents an average of 3 replicates and error bars indicate standard error. (B) and (C) GENCODE v27 transcript abundances were estimated using Salmon. Read Counts and R2 values for the linear fit are shown. The NEBNext kit provides superior depletion of rRNA from FFPE (degraded) samples and offers the flexibility of lower total RNA input amounts. Transcript expression correlation is consistent after treatment and regardless of input amount.




Figure 5: The NEBNext rRNA Depletion Kit v2 depletes both mature and pre-rRNA from human total RNA



Human universal reference total RNA (1 µg) was depleted of rRNA using the original NEBNext rRNA Depletion Kit (Human/Mouse/Rat) (NEB #E6310) and the NEBNext rRNA Depletion Kit v2 (Human/Mouse/Rat) (NEB #E7400). RNA-seq libraries were prepared using NEBNext Ultra II Directional RNA Library Prep Kit for Illumina followed by paired-end sequencing (2 x 75 bp). 10 Million reads were sampled (seqtk) from each library. Reads were identified as ribosomal using mirabait (6 or more shared 25-mers) with rRNA sequences for 5S, 5.8S 12S, 16S, 18S, 28S and ETS/ITS as baits. Levels of rRNA remaining were calculated by dividing matched reads by the total number of reads passing instrument quality filtering. The data represents an average of 3 replicates. NEBNext rRNA Depletion Kit v2 provide superior depletion of rRNA.
