TLA-based Services for Genetic Engineering

With a dedicated team of PhD-level scientists and nearly a decade of experience in the field, Cergentis is your trusted partner for the complete genetic characterization of genetically engineered cell lines, animals and cell therapy products.

We provide both routine and tailored services based on our proprietary TLA technology for targeted complete Next Generation Sequencing of genes and transgenes of interest across 100kb, in a single TLA experiment.

Our analyses are always carefully designed in close consultation with our customers.

Pricing for standard TLA service projects start at €2,650 per sample* and include the following:

  • TLA prep and amplification
  • NGS prep and sequencing
  • Data analysis
  • Reporting


See example reports for: CHO cells,         transgenic mouse line (homologous recombination),       trangenic mouse line (random integration)        transgenic human cell line (random integration)

The standard turnaround time is 6 weeks from receipt of the samples and relevant sequence information. We also offer expedited services with a turnaround time of 4 weeks, in case you desire even quicker access to your results.


Cergentis offers a personal dashboard for real-time project statuses, relevant documents and secured submission and storage of sample data and results.

Our expertise lies in the analysis of (complex) genetic engineering projects in various organisms and sample types, including CHO, human cell lines (T cells, HEK293, HeLa, etc.) and transgenic animals (mice, rats, goats, pigs, etc.).

In addition to TLA, Cergentis offers a range of services to further characterise your transgenic and genome-edited model, including:

  • Plasmid or vector sequencing
  • Genotyping primer design
  • Clonality Assurance Package (see below)
  • Genetic Stability Package (see below)
  • Premium Package (see below)
