AAV Characterization
AAV Characterization
The development of cell and gene-based therapeutics like AAV (adeno-associated virus) vectors has gained significant importance in recent years. We provide a comprehensive list of analytical methods for an in-depth characterization of your AAV construct. Through a targeted analysis setup of long read next-generation sequencing (ONT), quantitative PCR (qPCR), transmission electron microscopy (TEM) and LC-MS/MS techniques, we will provide you detailed information about the genome integrity, capsid surface and empty/full ratio characteristics of your product.
Our routine experts in sequencing and capsid protein characterization will guide you through the variety of available methods and help you find the optimal analytical solution for your project.
In accordance with your needs, we adapt and, if required, qualify (according to ICH guidelines) our platform methods tailored to your product, its individual formulation matrix and your distinct analytical question.
