| fluor spar | <chemical> Calcium fluoride, a mineral of many different colours, white, yellow, purple, green, red, etc, often very beautiful, crystallizing commonly in cubes with perfect octahedral cleavage; also massive. It is used as a flux. Some varieties are used for ornamental vessels. Also called fluor spar, or simply fluor. Source: Websters Dictionary (01 Mar 1998) |

| fluorescamine | <chemical> A nonfluorescent reagent for the detection of primary amines, peptides and proteins. The reaction products are highly fluorescent. Pharmacological action: indicators and reagents. Chemical name: Spiro(furan-2(3H),1'(3'H)-isobenzofuran)-3,3'-dione, 4-phenyl- (12 Dec 1998) |
| fluoresce | 1. To produce or exhibit fluorescence. 2. 4-phenyl[furan[2H(3H)-1'-phthalane]-3,3'-dione;a reagent that reacts with amino acids to procude a fluorescing compound. (05 Mar 2000) |
| fluorescein | <chemical> Fluorophore commonly used in microscopy. Fluorescein di acetate can be used as a vital stain or can be conjugated to proteins (particularly antibodies) using isothiocyanate. Excitation is at 365nm and the emitted light is green yellow (450-490nm). The emission spectrum is pH sensitive and fluorescein can therefore be used to measure pH in intracellular compartments.

| fluorescein angiography | <procedure> The process of taking X-rays of blood vessels that have been injected with a special dye. The dye allows to person viewing the X-ray to see the blood vessels. (13 Nov 1997) |
| fluorescein eye examination | A special test that allows the examiner to detect cornea abrasions or corneal foreign bodies. An orange dye (fluorescein) is placed into the eye and the eye is illuminated with a cobalt blue light (black light). This serves to highlight any irregularities in the corneal surface. (27 Sep 1997) |
| fluorescein instillation test | A test for patency of the lacrimal system; fluorescein instilled in the conjunctival sac can be recovered from the inferior nasal meatus. Synonym: Jones' test. (05 Mar 2000) |
| fluorescein isothiocyanate | <chemical> A fluorescent chemical derived from fluorescein which is used to label proteins. (25 Jun 1999) |
