1 The Vector

1.1 Specificity of MuLV

An important aspect for the function of our system as well as for its safety is the specificity of the vector regarding infection of different kind of cells. The vector deriving from the murine leukemia virus is specific for cells carrying the mouse specific CAT-1. Cells that do not have this specific receptor are not targeted by the vector. In order to test the specificity of the system, different kind of cells were incubated with the vector..

Fig.X: Scheme for testing the specificity of the vector.

In order to test the specificity of the viral vector different cells were incubated with the vector for four hours. Cells not containing the mouse specific receptor CAT-1 are not capable for infection. As control mouse fibroblasts (NIH3t3) expressing CAT-1 were used.
