摘要: The present invention includes a method and apparatus for measuring the transport of an analyte through cell membrane. One or more cells expressing plurality ion channels are provided. These loaded with so that contain at least 10 picograms within volume defined by area x-ray excitation beam depth five times 1/e attenuation one characteristic signal as attenuated water. unloaded is removed amount in measured fluorescence.
