Rapid selection of tetracycline-controlled inducible cell lines using a green fluorescent-transactivator fusion protein.

Journal Article (Journal Article)

We describe a modification of the tetracycline-controlled expression system that facilitates the rapid identification of tetracycline-sensitive clones. The TetR/VP16 transactivator protein was tagged with the green fluorescent protein (GFP) at its N-terminus. This results in a functional transactivator which allows cells expressing high levels of the modified transactivator to be selected by fluorescent-activated cell sorting. After expansion, single cell clones that maintain a high level of GFP fluorescence can be tested for their ability to transactivate a luciferase gene under control of the Tet operator, leading to the rapid identification of clones with strong inducibility.
