The world's most flexible rRNA depletion solution for your species  

riboPOOLs' unique feature is their high complexity pooling approach based on our Pack Hunter design algorithm.
The high complexity of riboPOOLs ensures optimal and maximum rRNA coverage, allowing for efficient and cost-effective rRNA removal of any species or abundant RNA.
riboPOOLs are available for single species (e.g., Homo sapiens, Drosophila melanogaster, etc.) and multiple species.

How do riboPOOLs work?

riboPOOL Pack Hunter Approach

How the Pack Hunter Approach improves specificity and reliability of ribosomal RNA depletion with riboPOOLs

riboPOOLs are highly complex and defined oligo pools containing 60-350 distinct biotinylated DNA probes. riboPOOLs have significantly improved rRNA removal efficiency and result in robust and reproducible RNA-Seq libraries.

This is attributed to 3 key features:

High-complexity pooling
Increased diversity of riboPOOL probe sequences ensure maximum target coverage. Additionally, the low concentration of individual probes leads to higher specificity and efficiency.

Detailed Bioinformatics Design
We ensure maximum and optimal rRNA coverage, optimal binding to rRNA sequences, and avoidance of targeting similar genes.

Quality Production Process
We manufacture and maintain our riboPOOLs in accordance with strict Quality Management standards. HPLC is used to refine riboPOOLs to ensure the highest purity levels.

rRNA depletion for your species


The Pan-riboPOOLs are a versatile rRNA depletion solution that allows for simple mono- and multitranscriptomic studies using a single-step rRNA depletion for a phylogenetic group (e.g., bacteria, fungi, or mammals).

The option to combine riboPOOLs facilitates single-step rRNA depletion in mixed samples such as environmental, blood, or infected tissue (e.g., SARS-CoV-2) samples. The so-called combination riboPOOLs enable simple metatranscriptomics studies by combining 2-4 riboPOOLs of non-related species.

Single-Species riboPOOLs

Single-species riboPOOLs are available for well-studied and lesser-known species (Escherichia coli, Arabidopsis thaliana or Schmidtea mediterranea and many more). Single-species riboPOOLs are specifically designed based on the species' rRNA to target both conserved and non-conserved regions.

Moreover, single species riboPOOLs are used on high quality to medium quality RNA and result in high rRNA depletion efficiency.

Simple workflow with riboPOOLs

riboPOOL Workflow

The riboPOOL workflow has four main steps:
1. Preparation of streptavidin-coated magnetic beads and riboPOOL
2. Hybridization of riboPOOL to target RNA
3. rRNA depletion
4. RNA Clean up.

All four steps can be completed within 70 minutes.

Achieve a fast and easy rRNA removal with riboPOOLs thanks to a hybridization-based workflow.

Our riboPOOL workflow allows a wide RNA-input range between 10 ng and 3 µg. When using >3 μg of total RNA for rRNA removal, please contact us for tips and tricks.

A huge benefit from our hybridization-based rRNA depletion approach is a higher correlation (R > 0.9) between non-depleted and depleted samples. Moreover, the riboPOOL workflow is completely automation-friendly.

riboPOOLs Special Applications

riboPOOLs can be customized to fit your RNA samples. We create riboPOOLs for any mixture of RNA (e.g., Seawater samples), strongly degraded RNA (i.e., FFPE samples), or ribosome profiling (Ribo-Seq) samples

FFPE samples & degraded RNA samples

Representative Bioanalyzer Analysis of RNA with varying RNA Quality

Total RNA extracted from FFPE tissue (Formalin-fixed, paraffin-embedded tissues) are heavily degraded, with RIN values below 2.
Due to their strong fragmentation, ribosomal RNAs are difficult to remove before RNA sequencing (RNA-Seq).
With a gapless and tiled probe coverage of the entire rRNA sequence, siTOOLs Biotech developed an efficient rRNA depletion tool for FFPE and other strongly degraded RNA samples.
We currently have human, mouse/rat, Caenorhabditis elegans, and Drosophila melanogaster riboPOOLs for degraded RNA samples.

Ribosome Profiling (Ribo-Seq)

rRNA DEpletion with riboPOOLs
Ribosome Profiling (Ribo-Seq) identifies actively translated RNAs by sequencing only those 30-base mRNA fragments protected by ribosomes.
The nuclease digest, degrading unprotected mRNA outside of ribosomes, also generates highly abundant ribosomal RNA contaminations, making up many sequencing reads.
siTOOLs Biotech has generated an efficient Ribo-Seq riboPOOL targeting primarily those extremely abundant rRNA contaminants commonly found in Ribo-Seq samples.
The entire rRNA sequence is covered with capture probes to deplete any less abundant rRNA fragment.
Our Ribo-Seq riboPOOL portfolio includes rRNA removal solutions for human, mouse/rat, Drosophila melanogaster, and Caenorhabditis elegans Ribo-Seq samples.

What Customers Say:


RNA Sequencing

“Our group works with halophilic archaea and the main challenge for prokaryotic transcriptomics is the low rRNA:mRNA ratio. siTOOLs Biotech has custom-design probes that target Haloferax volcanii (HVO) and the Pan-Archaea riboPOOL for ribodepletion in a broad spectrum of archaea. Both riboPOOLs efficiently depleted > 90% of rRNA across the different species of halophilic Archaea (Halobacterium salinarum, Haloferax mediterranei and Haloarcula hispanica). The use of rRNA removal kits, like riboPOOLS can greatly help facilitate rapid progress in understanding the transcriptional response of a wide diversity of archaea to their environment”.
Dr. Mar Martinez-Pastor (Senior Scientist, Schmid Lab, Duke University)
Publication: Pastor et al. (2022) Biomolecules

Oxford Nanopore Sequencing

"We have tried Thermo RiboMinus Plant Kit and riboPOOL probe targeting Pan-plant to remove rRNA. It is necessary to perform two rounds of rRNA depletion with Thermo RiboMinusTM Plant Kit. Only one round is needed for riboPOOL probe." 
Y. Long (Institute of Plant and Food Science, School of Life Sciences, Southern University of Science and Technology, Shenzhen, China)

Ribosome Profiling (Ribo-Seq)

"We are doing a lot of ribosome profiling experiments - mainly using mouse tissues and cell lines - and were in need of a ribosomal RNA depletion tool that was robust, economical, and adaptable.
Initially, we asked siTOOLs Biotech to design specific antisense probes against the most abundant rRNA contaminants that we tended to see in our ribosome profiling data, and that severely reduced the amount of usable reads.
The probes reduced the ribosomal RNAs they were designed for very well, however (and probably as to be expected) other rRNA contaminants subsequently became predominant and we needed a more uniform, rational tool that would cover all rRNA contaminants. 
Hence, siTOOLs Biotech designed and produced a ribosomal RNA depletion kit depleting both extremely abundant rRNA contaminants and less abundant ones.
We are very happy with the support, reactivity, and overall scientific expertise and knowledge of the siTOOLs team, which allowed us to have a great tool for a variety of experiments ongoing in the lab."
