K+channels, a superfamily of ∼80 members, control cell excitability, ion homeostasis, and many forms of cell signaling. Their malfunctions cause numerous diseases including neuronal disorders, cardiac arrhythmia, diabetes, and asthma. Here we present a novel liposome flux assay (LFA) that is applicable to most K+channels. It is robust, low cost, and high throughput. Using LFA, we performed small molecule screens on three different K+channels and identified new activators and inhibitors for biological research on channel function and for medicinal development. We further engineered a hERG (human ether-à-go-go-related gene) channel, which, when used in LFA, provides a highly sensitive (zero false negatives on 50 hERG-sensitive drugs) and highly specific (zero false positives on 50 hERG-insensitive drugs), low-cost hERG safety assay.
