MERCURIUS™ High Sensitvity BRB-seq kit

RNA-seq library preps from low-input, degraded and single-cell samples.



The MERCURIUS™ High Sensitivity BRB-seq kits contain all the oligos and enzymes needed to low-input RNA samples to high-quality gene expression data.

The generated 3' mRNA-seq data is ideally suited for differential gene expression analysis on small or degraded samples, such as single-cells, single-organoids and FFPE RNA samples.

As compared to other bulk 3' mRNA-seq solutions, BRB-seq makes it possible to process up-to 384 samples in one single tube, which helps to drastically reduce technical variation, turnaround times and costs. 

The particular aspect of the High Sensitiviy BRB-seq workflow is the use of a highly optimized protocol and modified TSO oligos, which enables a very low limit of detection.

Each kit contains enough reagents (including Unique Dual Indexing oligos) to prepare up-to three sequencing libraries.

After sequencing, the generated data can be easily demultiplexed and aligned to the genome of choice using our dedicated cloud-based pipeline, which does not require prior bioinformatic experience.

How to use our positive control RNA

  • Each BRB-seq kit contains reagents (including three pairs of Unique Dual Indexing adapters) sufficient for the complete library preparation process for three different BRB-seq pools.

    To note, the total number of RNA samples that can be processed with one kit does exceed the kit specifications; for instance, a 96-samples kit can be used to prepare up-to 96 samples distributed across up-to three different libraries.

  • The recommended range of input material is in the range of 5’000-50’000 cells.
  • The only difference between BRB-seq and standard RNA-seq data analysis is the demultiplexing step, which is used to assign sequencing reads to their sample of origin based on the BRB-seq barcode sequence.

    For a thorough description of BRB-seq data processing, please refer to the BRB-seq kit user guide. In order to facilate as much as possible BRB-seq data analysis, we have also created a dedicate pipeline which can be found in our “SOFTWARE” page.

  • One of the key advantages of BRB-seq is that it does not only save reagents and cost in the library preparation stage, but also in the sequencing one.

    As opposed to standard RNA-seq, where 20M-30M reads per sample are required, we normally recommend to sequence Cell Lysate BRB-seq libraries at a depth of 1M-2M reads per sample, which is normally enough to accurately detect up- or down- regulated pathways in a screening context.
