Example 3

Cells transduced with Lenti-GFP as explained above were analysed on a Sony SH800Z flow cytometer with 488 laser. Signal from GFP transduced cells was compared with untransduced cells. The results are shown in FIG. 5. This demonstrates that transduction works.

Constructs expressing irrelevant VH with a HIS tag were shown by flow cytometry to have surface expression on Jurkat cells using anti-His detection agents. This shows that the leader sequence directs the CART to the surface of the cell as expected.
