Wyss researchers have created a high-throughput platform to generate an Adeno-associated virus 2 (AAV2) library containing 200,000 variants, each carrying a distinct mutation in the virus capsid protein. Their analysis identified capsid changes that enhanced “homing” potential to specific organs in mice and virus viability, as well as a new protein hidden in the capsid-encoding DNA sequence.
