AAV Analysis

Adeno-Associated viruses (AAV) are one of the go-to vectors for the delivery of therapeutic genes in gene therapy. As gene therapy holds the key for the treatment of a wide variety of diseases, its success stands and falls with the safety and efficacy of the utilised vectors.

We offer a comprehensive investigation of your AAV particles, focusing on key attributes essential for the optimal performance of your gene therapy vectors:





  • Particle Morphology
  • Particle Integrity
  • Aggregation levels and distribution
  • Process impurities
  • Full/Empty Ratio Determination


We are currently validating our AAV analysis using negative staining TEM and Cryo-TEM for full GMP release of your AAV vectors.

Results and the corresponding Final Reports (CoA) are issued within 15 working days.
