Our genetic QC solutions

Our genetic QC solutions

Modern gene editing techniques have redefined the boundaries of biological research, allowing novel cell and gene therapy approaches to combat life-threatening diseases and provide renewed hope to patients.
However, genome editing can still result in undesired outcomes which can be difficult to characterize, and failure to do so can have significant health and financial consequences.
Our TLA-based genetic QC solutions fill a significant gap in the genetic diagnostics market and have been repeatedly endorsed in public literature.

1. What are some of the most important QC needs in genetic research?

Cergentis provides robust genetic characterization through proprietary TLA-based genetic QC solutions. Our assays have been used in thousands of projects to reliably determine gene editing outcomes in a variety of organisms and cell lines by leading pharma, biotech and renowned research institutes.  We provide comprehensive genetic assessment and targeted sequence analysis of (trans)genes to help our customers select and characterize genetically engineered cell lines, animals and biopharmaceutical products.

2. Why opt for TLA-based genetic QC solutions?

a. Unmatched genetic insights

In one experiment, our TLA-based genetic QC solutions can identify vector insertion sites and potential sequence variants, from individual nucleotide variants to large structural rearrangements, on- or off-target. TLA can robustly identify all genetic variation in and around (trans)genes of interest, something that more conventional approaches such as WGS, PCR, FISH or Southern Blot struggle to do. For more information, we invite you to check our comparison table. Since our landmark Nature Biotechnology (2014) publication, our TLA-based method has been widely applied across several application areas to genetically characterize genetically engineered cell lines and modified organisms. To date, our unrivalled genetic QC solutions have been extensively endorsed in over 50 peer-reviewed publications.

b. Included in regulatory filings and favorably reviewed by FDA

ATMP (advanced therapy medicinal product) development requires thorough genetic characterization for development and commercialization. Your filing will require solid evidence and detailed documentation of the genetic characterization your product(s). Genetic QC is heavily monitored by FDA and EMA officials and may significantly influence their decision.
That’s why our detailed TLA reporting complies with FDA and EMA requirements (ICH guidelines Q5B and Q5D, CTD Quality module, section 3.2.S.2.3) and is suitable for inclusion in regulatory applications for pharmaceuticals for human use.

TLA data has been used for both early and late stage trials, for a range of processes:

  • Early stage (phase I, IND/NDA)
  • Late stage (phase III, BLA)
  • (Master) Cell Bank characterization
  • Genetic stability analysis
  • Clonality assessment
