Cell & Gene Therapy
Cell and gene therapies are important novel approaches to activate immune response, repair pathogenic mutations, and to repair or replace damaged tissue or cells. Ensuring correct genetic modification of these products is key in ensuring safe and effective therapies.
Cergentis' TLA technology contributes to upstream and downstream stages of cell and gene therapy product development and production.
Quality control in the upstream process
TLA analyses support:
- The optimisation and validation of new cell line generation technologies
- Clone selection
- Clonality and genetic stability analyses
Quality control in the downstream process
In downstream processing of gene and cell therapy products, TLA can map viral integration sites and quality control the results of targeted gene editing.
TLA-based targeted sequencing is used to:
- Quantify the number of correct and incorrect integration and/or gene editing events at an intended location
- Assess the targeting of a CAR to the TRAC locus
- Completely sequence the HIV genome and determine integration sites in a patient's blood sample
- Evaluate transfected/transduced immune cell samples (e.g. T- and B-cells). For example, towards the development of CAR-T cell therapies
