Viral Vector Identity Testing

Identity testing is a key quality control process in the production of GMP viral vectors to confirm the identity and purity of viral vectors during production. Creative Biogene has developed a range of platform technologies and testing protocols to test the identity of viral vectors to ensure the safety and efficacy of viral vector products produced under GMP conditions.

Viral Vector Identity Testing

Why Identity Test of Viral Vectors is Important?

Identity test is essential in ensuring the safety and efficacy of viral vector products produced under GMP conditions, as any deviation from the intended genetic construct could have deleterious effects on the efficiency and safety of the product. Thus, identity testing is an essential part of GMP viral vector production quality control testing, which helps to ensure the safety and efficacy of viral vectors used in clinical applications.

Viral Vector Identity Testing Strategy at Creative Biogene

Identity testing of viral vectors assesses the presence or absence of a specific genetic marker or sequence on the vector, confirming that it exactly matches the expected genetic structure. This confirms that the vector is consistent with the specifications and will remain stable throughout its shelf life. Creative Biogene, with our extensive experience in quality control of GMP viral vector production, performs a comprehensive analysis of viral vector identity testing in the following areas:

  • Vector copy number by qPCR
  • Vector insert identity & stability
  • Insertional site analysis
  • ADA isoenzyme analysis

Identity Testing Method for Virus Vectors

Identity testing is an important quality control point, and we offer a variety of advanced analytical techniques to accurately test viral vectors for inter-batch consistency, purity, and contaminants to confirm vector identity.

MethodDescription
Polymerase chain reaction (PCR)A highly sensitive and specific technique for detecting viral DNA and RNA sequences that allows efficient identification of viral vectors during the production process.
Southern blottingSouthern blotting is a technique used to identify specific viral DNA sequences in a sample. This method is particularly useful for detecting viral genome integration, which is a potential safety concern.
Whole genome sequencingWhole genome sequencing is a powerful tool for identifying and characterizing viral vectors. This method can be used to detect mutations and variations in the viral genome, as well as confirm the identity of the viral vector.

Creative Biogene leverages our high-sensitivity platform technology to perform rigorous identity testing during GMP viral vector production and quality control prior to release. The safety and efficacy of viral vectors are ensured through accurate testing and identification.
