Streamlining AAV analytics in gene therapy manufacturing workflows

AAV analytics in GMP-regulated environments


AAV manufacturing environments are GMP-regulated and subject to a series of rules established by agencies  such as the US Food and Drug administration (FDA) and the European Union (EU). These regulations require that any software used in AAV manufacturing workflows have features that ensure data traceability and reproducibility.  In addition, instruments to be used within AAV manufacturing processes need to be qualified at different stages of production and implementation. These qualifications include design, installation and operational qualifications (DQ, IQ, OQ).


New AAV analytical technology now available for use in AAV manufacturing workflows

SamuxMP, the mass photometer tailored for AAV analytics, can be used in GMP-regulated environments as it has a compliant software that fulfills the FDA and EU requirements for AAV manufacturing including:


  • User management and access control, including several privilege levels

  • Full data traceability, unique ID assigned for each raw dataset

  • Detailed audit trail and electronic signatures for full accountability



The Refeyn service teams also provide installation and operational qualifications for instruments destined to AAV manufacturing facilities, including documentation and training upon request

Streamlined, reproducible workflows for AAV characterization in GMP-regulated environments

Refeyn’s software package for AAV manufacturing environments includes automated workflows to streamline data analysis, as well as standardize it between operators. In the automated mode, mass ranges are automatically defined to classify detected AAVs into empty, full and partially filled populations.


These ranges are automatically defined based on user inputs for the expected mass of the empty capsids and the size of the genomic payload. Manual and semiautomated modes are also available for users with advanced permissions.
