LumiCycle performs high-throughput luminometry on self-luminous tissues, such as those from transgenic animals containing the luciferase gene. The system is equipped with 4 photon-counting photomultiplier tubes, each selected for low dark counts and high sensitivity in the green portion of the spectrum at which luciferase emits light. 32 tissue samples, each in a 35 mm Petri dish, can be counted at one time. 8 dishes share each photodetector using a turntable device that alternately brings each dish under the detector, one at a time.
