Unveiling the secrets of adeno-associated virus: novel high-throughput approaches for the quantification of multiple serotypes.

Adeno-associated virus (AAV) vectors are among the most prominent viral vectors for gene therapy, and their investigation and development using high-throughput techniques have gained increasing interest. However, sample throughput remains a bottleneck in most analytical assays. In this study, we compared commonly used analytical methods for AAV genome titer, capsid titer, and transducing titer determination with advanced methods using AAV2, AAV5, and AAV8 as representative examples.
