DNA and RNA sequencing

From sample to publication-ready data.

We handle the whole process - from material extraction, through library preparation and NGS and TGS sequencing, to advanced bioinformatic analysis.

SEQUENCING IS OUR SPECIALITY

Order DNA or RNA sequencing.

We specialise in next-generation sequencing (NGS) with short reads and third-generation sequencing (TGS) with long reads. We sequence on Illumina, PacBio and Oxford Nanopore Technologies platforms, using the latest instruments such as the Illumina NovaSeq X Plus and the PacBio Revio.

With us you can study the transcriptome, genome, epigenome and microbiome, and run single-cell analyses. Beyond sequencing, we advise you at the experiment planning stage and carry out a complete bioinformatic analysis of the results.

Laboratory centrifuge with rotor and tubes - DNA and RNA extraction for NGS

Genetic material extraction

We extract DNA and RNA from almost every kind of biological material - from standard samples to exceptionally demanding ones. We also specialise in working with degraded samples and with samples containing very little genetic material. We handle material of high scientific value too, such as fossils and historical samples.

Every extraction is carried out by an experienced team using validated methods and rigorous quality control.

Once the analyses are complete you receive a report covering the quality and quantity of the extracted material.

Sequencing library preparation

Every NGS analysis begins with preparing a DNA or RNA library. At this stage the genetic material is precisely converted into a form compatible with the sequencing platform, through fragmentation, adapter ligation and - depending on the project - amplification and purification.

The process is based on validated protocols and a high degree of automation, which reduces the risk of human error and ensures maximum reproducibility and input data quality.

Genomic data visualisation - bioinformatic analysis of NGS sequencing results

Bioinformatics analysis

Sequencing produces large and complex data sets that require specialist processing and proper interpretation. Our bioinformatics team analyses the data from your samples and turns it into clear, well-organised and usable results.

Depending on the type of project, the analysis may cover the identification of genes and transcripts, detection of variants and mutations, assessment of genetic variation and genome structure, gene expression analysis, characterisation of microbiome composition, and comparisons between samples or study groups.

Every project ends with a clear report describing the methods used, the results, tables and suitable visualisations such as charts, diagrams or heat maps. The materials you receive are ready to use in publications and can also serve as a basis for further interpretation or subsequent analyses.

FAQ

Frequently asked questions.

We are not just an NGS service provider. We are a research partner who helps you plan the experiment, reduce the risk of costly mistakes and obtain the data that best matches your project's aims. Our support covers the whole process - from the first consultation, through sequencing and bioinformatic analysis, to help after the results are delivered.

The cost of sequencing depends on the specifics of the project - the type of analysis, the number of samples, the technology chosen, the required read depth and the scope of the bioinformatic analysis. That is why we do not use a universal price list - we quote every project individually.

To prepare an accurate offer, fill in the short form. Based on it we will select the optimal project specification, prepare a free quote and give you the expected turnaround time.

Turnaround time (TAT) depends on many variables, so we set it individually and state it bindingly in the offer, before work begins. It is affected by the scope of the order (extraction, library preparation, sequencing, bioinformatic analysis - the more stages, the longer it takes), the type of analysis (different methods need different instruments; small RNA-seq, for example, usually takes a few days longer than mRNA-seq), the amount of data and how it is delivered, and the quality of the samples provided (if even one fails QC, the analysis waits for your decision on that sample).

If you are settling a grant with a tight deadline, note it in your enquiry - we will propose a schedule that fits. More in the knowledge base: Service delivery time (TAT).

Full rights to the data and the results remain yours - we do not use them for any other purpose.

We share results through an encrypted cloud with infrastructure located in the European Union and compliant with GDPR. Data is transferred over TLS/SSL, encrypted with AES-256 and replicated across several data centres, which ensures high availability and removes any single point of failure.

Access to the results is only through a secured link. On request we also sign a non-disclosure agreement (NDA).

The factor that determines the quality of the results is the input material for library preparation, so sample quality is critical. If you are struggling with poor sample quality, we offer a nucleic acid extraction service - an automated procedure that gives reproducible results and reduces human error.

If you cannot verify the quality of your material before shipping, or if you often work with difficult material, use the QC Contingency Package - Backup: it lets you send up to 20% more samples for QC analysis, and once you have the results you decide which of them (up to the number in your order) go into library preparation - with no extra QC cost for the surplus samples.

More in the knowledge base: DNA or RNA extraction and QC contingency package - Backup.

Yes, and there are two ways to do it, depending on what you need.

1. Spare samples (free option)
You add surplus samples to the shipment. We only reach for them if your primary samples fail quality control (QC) - saving you time and the cost of shipping another batch of material.

2. QC Contingency Package - Backup (paid option)
You send up to 20% more samples than in your order. We run quality control (QC) on all the samples received, and you decide - based on the finished results - which ones go for sequencing.

We have described the full rules of the second option (including billing) in the knowledge base: QC contingency package - Backup. It is worth a look before you order, so you can choose the best option for your project.

Yes, it is an essential part of every order. For DNA/RNA samples we check quality three times: on receipt, after library synthesis and after sequencing.

More in the knowledge base: Quality control.

Yes, you will find example bioinformatic analyses in our knowledge base: Bioinformatics analysis.
