Abstract: Samples are exposed to a fluorescent probe that binds to a known target analyte. Unbound probe is removed and the sample is exposed to a pulsed laser light of preferred wavelength, where the laser light is split into background and sample beams, which are separately measured by two photomultiplier tubes connected to a gated scanning dual channel photon counter Measurements are made by time-resolved photon counting, where individual photons are detected and counted as an electronically synchronized function of the time after each light pulse, and data are summated over a number of light pulses, to detect and quantify the target analyte.

Abstract: This invention is a transportable organ preservation system that substantially increases the time during which the organ can be maintained viable for successful implantation into a human recipient. A chilled oxygenated nutrient solution is pumped through the vascular bed of the organ after excision of the organ from the donor and during transport. The device of the present invention uses flexible permeable tubing to oxygenate the perfusion fluid while the CO.sub.2 produced by the organ diffuses out of the perfusion fluid. One pressurized two liter “C” cylinder that contains 255 liters of oxygen at standard temperature and pressure can supply oxygen for up to 34 hours of perfusion time. The device uses a simple electric pump driven by a storage battery to circulate the perfusion fluid through the organ being transported. The vessel containing the organ to be transported is held at 4.degree. C. by coolant blocks.
