title: A new optical multichannel microspectrofluorometer.
abstract: A new microspectrofluorometer has been developed that combines a photometric fluorescence microscope with an optical multichannel analyzer. This instrument provides fluorescence emission spectra of biological materials by detecting the entire spectrum simultaneously in real time. These spectra are subsequently recorded and corrected so as to identify the fluorescent reaction products or to test whether fluorescent cytochemical probes bind to the expected substrate within cells. The procedures and advantages of optical multichannel analysis are described, and an application of microspectrofluorometry to acriflavine-Feulgen cytochemistry is given.
