Proteomic Landscape of Adeno-Associated Virus (AAV)-Producing HEK293 Cells

Adeno-associated viral (AAV) vectors are widely used for gene therapy, providing treatment for diseases caused by absent or defective genes. Despite the success of gene therapy, AAV manufacturing is still challenging, with production yields being limited. With increased patient demand, improvements...
