What we do


High sensitivity BRB-seq Service

The MERCURIUS™ High sensitivity BRB-seq service offers a convenient and streamlined solution for transcriptomics projects with a limited input amount of RNA (starting from 100pg per sample).

Clients can send us purified RNA samples, which are always quality-checked before launching our BRB-seq pipeline. During the process, we always keep clients informed at the defined checkpoints so that we can decide together how to best proceed to the next steps.

Next-generation sequencing and data pre-processing (including alignment to the genome of choice) are also part of our standard service. As a result, we provide our clients raw data, sequencing and alignment reports, and gene count matrices which can be used for downstream gene expression analysis.

  • 1 week

    Incoming QC - Client Checkpoint

    (Nanodrop, Ribogreen, Tapestation)
  • 2 days

    MERCURIUS™ High sensitivity BRB-seq library preparation for Illumina®

  • To guarantee high quality data, we normally request that each sample contains at least 200ng of total RNA in at least 10μl.
  • In addition to total RNA amount, it is important that the samples contain RNA of high integrity (RIN > 6) and are devoid of contaminants (Nanodrop A260/A230 between 1.8 and 2.2).
  • BRB-seq is 3’-end RNA sequencing method and, as such, requires significantly less sequencing as compared to standard full-length RNA-seq in order to reach accurate gene quantification. We therefore normally recommend to sequence 4 to 5 million reads for each sample, which enables the reliable and unbiased detection of over 18’000 genes.
  • As part of our standard service pipeline, we align the generated data to the genome of choice, provide a detailed report on the alignment and gene counting statistics and, finally, provide ready-to-use gene count matrices for downstream analysis.
