ABSTRACT:
A fluora immuno assay system. A fluorescent labeled assay reagent is prepared by conjugating an assay reagent with a fluorescent labeling agent. The fluorescent labeling agent is a chlorophyll or a porphyrin having a Stokes shift of not less than 150 nanometers. Apparatus for detecting the presence of the labeling agent comprising an excitation source illuminating a vessel with a photodetector directly within the illuminated area is also shown. The photodetector is insensitive to the spectrum of the excitation source.
