The invention provides fluorogenic compounds and probes that can be used as reagents for measuring, detecting and/or screening superoxide. The fluorogenic compounds of the invention can produce fluorescence colors, such as green, yellow, red, or far-red. The invention further provides fluorogenic compounds for selectively staining superoxide in the mitochondria of living cells. The invention also provides methods that can be used to measure, directly or indirectly, the presence and/or amount of superoxide in chemical samples and biological samples such as cells and tissues in living organisms, and a high-throughput screening methods for detecting or screening superoxide or compounds that can increase or decrease the level of superoxide in chemical and biological samples.

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.
