fluorapatite
- n a form of apatite in which fluorine predominates over chlorine
fluorescein
- n a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)
fluorescein isocyanate
- n a fluorochrome commonly conjugated with antibodies for use in indirect immunofluorescence
fluorescein isothiocyanate
- n a fluorochrome commonly conjugated with antibodies for use in indirect immunofluorescence
fluoresceine
- n a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)
fluorescence
- n light emitted during absorption of radiation of some other (invisible) wavelength
fluorescence microscopy
- n light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes
fluorescent dye
- n a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)
