small RNA sequencing services

For untargeted genome-wide analysis of microRNAs and other small RNAs, next-generation sequencing (NGS) is the platform of choice.

At TAmiRNA we are fully dedicated to microRNA and small RNA NGS analysis. As we mainly work with extracellular RNA in biomarker research, we have long-lasting experience with very low-input RNA samples such as:

Our in-house developed miND® spike-ins enable absolute quantification and ensure the highest data quality, while RNA input can be reduced down to 1 ng total RNA or less.

Our NGS services go hand-in-hand with our

What we offer: our service includes total RNA extraction, small RNA sequencing library preparation, next-generation sequencing, data analysis, and reporting. Depending on customer experience we can focus on individual tasks or provide a full service.

Our promise: our small RNA sequencing workflow has undergone analytical validation. With best-in-class precision and accuracy, we can ensure the highest data quality. By using TAmiRNAs miND spike-ins we can transform relative counts into absolute concentrations (molecules/µL of input RNA).

Our experience: we have conducted small RNA sequencing analysis with samples from the following organisms: human, non-human primates, mouse, rat, hamster (CHO), pig, cow, horse, chicken, dogs, as well as C. elegans and drosophila. For other organisms data analysis can be implemented upon request. Browse our published reference projects (below) for more information on previous projects.

Your data: we provide interactive reports (see video) that enable you to access and download your data so that it can be directly integrated into reports, publications, and presentations.

Your flexibility: we offer MiSeq, iSeq, NextSeq550, NextSeq1000/2000 and the NovaSeq. Thus, we manage to find a cost-effective solution for small and large projects.

sample requirements

Cells: we can go as low as 10-50 cells

Tissues: we can process everything from laser microdissected tissue compartments of just 10,000 µm2 up to frozen or fixated tissue blocks. Learn more about our workflow for space-resolved RNA profiling.

Biofluids: serum, plasma, urine, saliva, CSF, milk, synovial fluid. The standard input is 100-200 µl but can be optimized to meet your restrictions.

Extracellular vesicles: characterization of EV RNA cargo can be performed by NGS or RT-qPCR. Due to the heterogeneity of methods that are used for EV purification, we prefer to discuss your project individually.

service description

Small RNA sequencing includes several steps, which can all be performed at TAmiRNA:

  • Total RNA extraction: we have protocols for cells, tissues, biofluids and EVs. Leftover total RNA can be returned to customers for follow-up experiments.
  • Total RNA quality control: concentration and integrity using highly sensitive and specific fluorescence based methods
  • small RNA library preparation: we prepare high quality libraries using a circularization protocol. This reduce adapter ligation bias compared to other methods. In addition, we have developed a proprietary spike-in calibrator that is added to the library preparation and enables absolute quantification.
  • NGS analysis: using a wide-range of Illumina instruments (HiSeq, NextSeq, NovaSeq) we can pick the most efficient solution for each project.
  • Data analysis: we provide everything from raw data to fully analyzed data reports depending on customer needs.
