CAR-T cell therapies have emerged as a powerful tool in the fight against cancer, offering targeted treatment options for patients with otherwise limited alternatives. This application note unveils the detailed process of generating CAR-T cells, from plasmid design to functional validation. Utilizing cutting-edge e-Zyvec® DNA assembly technology and FectoVIR®-LV for lentiviral vector production, researchers constructed plasmids encoding CD19 CAR to transduce T cells and expand them ex vivo.
The results demonstrate the successful generation of CAR-T cells with potent anti-tumor capabilities, particularly against CD19-expressing cancer cells.
Key aspects of the methodology include optimized plasmid assembly, high-titer lentiviral vector production, and a robust cytotoxicity assay that showcases the CAR-T cells' ability to eliminate antigen-positive target cells. This study highlights the strategic integration of advanced molecular engineering techniques, resulting in efficient CAR-T cell production with promising therapeutic potential. These findings contribute to the growing body of knowledge surrounding gene-modified cell therapies and underscore the importance of precise, scalable processes to support the advancement of CAR-T therapies in clinical settings.
