A machine for automatic in vitro detection of analytes, the machine being of the type including an optical reader device capable of detecting the optical response of the reaction solution to electromagnetic stimulation using a photoelectric receiver that is carried by a movable carriage of the machine and that moves under automatic control in order to bring the photoelectric receiver into various positions, each corresponding to various respective analysis zones. The photoelectric receiver forms part of a spectrometer capable of delivering a chromatic spectral decomposition of the optical response. Also provided are methods of automatic in vitro detection and/or quantification of analytes. In one method, a chromatic spectral decomposition of the optical response is acquired and two distinct optical agents are detected separately using the spectral decomposition.

Machine and method for automated in vitro analyte detection by means of chromatic spectral decomposition of an optical response

A composition for enzyme immunoassay using immunofluorescence comprises (i) a fluorogenic enzymatic substrate and (ii) a quenched fluorogenic compound that forms a fluorescent compound after hydrolysis of the fluorogenic enzymatic substrate. The composition may be useful for performing a method for in vitro detection and/or quantification of an analyte of a liquid test sample liable to contain the analyte.
