    摘要: The present invention relates to methods for detecting the activity of an ion channel in a cell. The methods comprise providing a loading buffer solution to a cell that has an ion channel. The loading buffer comprises at least one thallium indicator (e.g., an environmentally sensitive, luminescent dye) and a physiological concentration of chloride ions. The methods further comprise providing a stimulus buffer to the cell, wherein the stimulus buffer comprises thallium (e.g., thallium ions). Providing the stimulus buffer causes thallium influx into the cell through the ion channel. After providing the stimulus buffer, the luminescence (e.g., fluorescence) of the dye in the cell is detected. The luminescence of the dye can change in the presence or absence of thallium. The methods may be used to measure influx or efflux of thallium through an ion channel.
