ACCELERATE PRODUCTION
Pathogen detection
We offer NGS and PCR-based pathogen detection assays with short lead times to accelerate process decisions.
Pathogen detection approaches
We develop assays for detecting pathogenic oncogenes or microbial contamination during production.
This risk of contamination is a constant concern in the production of cell and gene therapies, primarily because it’s impossible to sterilize the cells used in production or the raw materials. To minimize the risk of infection, it is crucial to utilize well-characterized cell lines that do not carry endogenous viruses with the potential to induce tumorigenesis. These cell lines must undergo testing for human pathogenic viruses such as HIV, Hepatitis B (HepB), Human Papillomavirus (HPV), Epstein-Barr Virus (EBV), and Cytomegalovirus (CMV).
At TATAA Biocenter, we can help screen for oncogenic sequences in cells used in production. In the case of autologous cells, extensive screening may only be necessary if the bioprocessing procedures increase the risk of oncogenic events.
Furthermore, the manipulation of cells carries a high risk of microbial contamination. In controlled engineering facilities, most organisms typically originate from the commensal flora of personnel, which is generally considered nonpathogenic but can lead to clinically significant infections in individuals with compromised immune systems. The most common microbial contaminants include mycoplasma, bacteria, and fungi. Detecting unidentified microbial contaminant species poses a challenge, and one potential solution is to consider 16S rRNA screening for prokaryotic contamination and 18S rRNA screening for eukaryotic contamination.
Accelerate production with TATAA
We offer short lead times and fast analyses, allowing you to optimize the purification process, provide confidence in your products before GMP analysis, help with deviation control, and ensure trust in GMP results and safe product delivery.

QUALITY ANALYSES
Accelerate with reliable results
With over 20 years of experience in nucleic acid analysis, we specialize in developing PCR-based assays that offer fast, accurate, and reliable quality testing for process optimization. The rapid results generated by PCR technology make it well-suited for assays on viable products, crucial for cell and gene therapies.
Vector copy number
Quantifying the transgene dosage, the presence of transgenes, the number of integrated vectors, or the number of non-integrated vector genomes in targeted cells provides essential information during production optimization.
Host cell DNA residuals
We use PCR approaches to detect DNA impurities from host production cells or plasmids used for transfection in gene therapy viral vector production.
Vector integrity
Ensuring consistent characterization of the packaged vector genome is crucial for production process optimizations and comparing results across production batches.
Integration site analysis
We evaluate the integration site specificity and transduction efficiency, assess safety, and prevent unintended effects on adjacent genes during integration.
Primer dimer test Primer-dimers can bias qPCR results, so a test for primer-dimers should be performed during assay development to ensure that only the target sequence is amplified and quantified. The effect of primer dimers Checking for primer dimers is
