Expression of bacterial potassium channels in eukaryotic host cells and their use for the identification of antibiotics

摘要

The subject matter of the invention are eukaryotic expression vectors, the expression of bacterial potassium channels enable the lct b family. Furthermore, according to the invention, these vectors containing enclosed host cells which express the bacterial potassium channels. Furthermore, the first time, a method for identifying substances is made available, the bacterial potassium channels opening, closing, modulating, can activate or deactivate and, thus, bactericides or bacteriostatic properties. According to a particular embodiment of the invention, the method for identifying or finding of antibiotics.
