Quality control for Adeno-associated viral vector production

Adeno-associated viral vectors (AAV) are frequently used by neuroscientists to deliver tools, such as biosensors and optogenetic and chemogenetic actuators, in vivo. Despite its widespread use, AAV vector characterization and quality control can vary between labs and viral vector cores leading to variable results and irreproducibility. This protocol describes some of the characterization and quality control assays necessary to confirm an AAV vector’s titer, genomic identity, serotype and purity.
