Fluorescent microspheres

Microsphere brochure

Triton Technology sells two types of fluorescent microspheres: Triton Technology Dye-Trak 'F' fluorescent microspheres and the Molecular Probes FluoSpheres®.

Fluorescent microspheres are a sensitive non-radioactive method of measuring regional blood flow by dye extraction.  After recovery of the microspheres from the harvested tissue samples, the dye is extracted and quantified by fluorescence spectrophotometry.  Fluorescent microspheres have been well documented in the literature.  

Use the Dye-Trak 'F' colors plus two FluoSphere colors to measure 6 colors with no need to do mathematical spill-over correction.  This is the most cost effective combination of fluorescent colors.  Best combination of six colors.

The new Dye-Trak 'F' fluorescent microsphers were recently evaluated by the University of Washington Fluorescent Microsphere Resource Center (FMRC).
