Vector genome integrity assays

We offer PCR-based vector genome integrity assays with short lead times to accelerate process decisions.

Vector integrity assessments

Vector integrity includes several assays to evaluate a gene therapy product’s quality, safety, and efficacy.

Vector genome integrity assesses whether the vectors remain intact and functional during production, purification, and administration, including tests for purity and identity. These assays provide insights into viral vector quality, safety, and efficacy, ensuring suitability for gene therapy.

Assessing integrity is crucial during development to correlate administered doses with potency and bioanalytical data. In clinical trials, the testing ensures the delivery of the specified genetic material to target cells.

Integrity testing encompasses various aspects, including transgene and vector completeness and robustness. We evaluate stability data in different conditions over time, quantify vector copy numbers for dosage and safety, and assess purity and sterility for safety. We perform integration site analysis to evaluate specificity and transduction efficiency, assess safety, and monitor unintended effects on adjacent genes during transgene integration.

To assess vector integrity, various techniques such as qPCR, dPCR, or NGS are employed to quantify and sequence viral vectors from biospecimens. These analyses contribute to gene therapy products’ overall safety and efficacy assessment.

Quantitative and digital PCR is used for vector integrity analysis due to its high sensitivity and specificity, allowing quantification of key genetic elements in the viral vector, such as ITRs. The data provides information about the integrity and concentration of the vector genome.

NGS provides a more comprehensive view of the vector genome, giving information about the overall composition of the vector genome and identifying any unexpected genetic alterations or contaminants.

Additionally, our facility includes a Biosafety Level 2 (BSL-2) laboratory that allows us to offer end-to-end solutions, from sample extraction to data transfer.

compliant bioanalysis

Accurate and reproducible data

A GLP accredited and GCLP compliant laboratory

TATAA Biocenter is accredited by the Swedish Board of Accreditation and Conformity Assessment (SWEDAC) for complying with Good Laboratory Practice (GLP) standards. We also adhere to Good Clinical Laboratory Practice (GCLP) guidelines, which are international quality standards governing the analysis of samples from clinical trials using GLP.

GLP and GCLP validation is mandatory in preclinical and clinical assays to demonstrate accuracy, reliability, and consistency. These standards cover every aspect of study planning, execution, monitoring, documentation, archiving, and reporting. This rigorous process assures both the sponsors, when submitting data for new drug approvals, and the regulatory authorities, when reviewing the data, that it is generated in a regulated manner.

method validation

Accelerate drug development with validated assays

Validated bioanalysis is essential throughout the entire drug development process.

Conducting fit-for-purpose validations in the initial stages of discovery is key. These validations offer valuable insights of expected assay performance before undertaking more comprehensive method validation processes. A validated PCR assay is essential to ensure the accuracy and reliability of results and ensures that the assay meets the client’s needs, study requirements, and assay criteria under defined operating conditions. Our assay validations ensure dependable data for making stage-gate decisions and preparing regulatory filings.

A validated assay is a valuable asset.


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.
