The light system

One advantage of our system, the spacial resolution by infecting only distinct areas in a mammalian cell culture with our viral vector, was archived by the use of different light systems. We managed to induce the expression of the mCAT-1 receptor in non-murine cell lines by illumination with light of a special wave length. Since, the viral vector only infect cells that express the mCAT-1 receptor on their surfaces, we transferred genes into distinct areas of a otherwise homogenous tissue using this principle.
