| 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-5-isothiocyanate | <chemical> 3',6'-dihydroxy-5-isothiocyanatospiro(isobenzofuran-1(3h),9'-(9h)xanthen)-3-one. Fluorescent probe capable of being conjugated to tissue and proteins. It is used as a label in fluorescent antibody staining procedures as well as protein- and amino acid-binding techniques. Pharmacological action: fluorescent dyes. Chemical name: Spiro(isobenzofuran-1(3H),9'-(9H)xanthen)-3-one, 3',6'-dihydroxy-5-isothiocyanato- (12 Dec 1998) |
| 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-conjugated antibody | Refers to an antibody that has joined with a fluorescein molecule. (09 Oct 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) |
| fluorescein sodium | A dye used for diagnosis of certain ocular diseases, differentiation or delineation of organ parts in surgery, and determination of circulation time. Synonym: resorcinolphthalein sodium, uranin. (05 Mar 2000) |
| fluorescein string test | A string test used to determine location of a bleeding intestinal lesion in which fluorescein is given intravenously to determine gastrointestinal haemorrhage; if the string fluoresces after removal, it has been contaminated by blood that has appeared since injection of the fluorescein; used to determine location of bleeding lesion. (05 Mar 2000) |
| 3-O-methyl-fluorescein phosphatase | <enzyme> Used for assay of na-k-atpase in intact tissues Registry number: EC 3.6.1.- Synonym: 3-o-methylfluorescein phosphatase (26 Jun 1999) |
| vaccines, conjugate | Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognised by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection. (12 Dec 1998) |
| wheat germ agglutinin-horseradish peroxidase conjugate | <chemical> The lectin wheatgerm agglutinin conjugated to the enzyme horseradish peroxidase. It is widely used for tracing neural pathways. Pharmacological action: molecular probes. (12 Dec 1998) |
| conjugate | Paired together. In chemistry, this refers to an acid and a base which can convert to each other by the gain or loss of a proton (a hydrogen nucleus), which together are called a conjugate acid-base pair. It can also refer to two liquids in equilibrium with each other. In mycology (the study of fungi), this refers to a dikaryon with two haploid nuclei in it. (09 Oct 1997) |
| conjugate acid | The protonated compound of two compounds that differ in structure only by the presence of the labile proton. (05 Mar 2000) |
| conjugate acid-base pair | In prototonic solvents (e.g., H2O, NH3, acetic acid), two molecular species differing only in the presence or absence of a hydrogen ion (e.g., carbonic acid/bicarbonate ion or ammonium ion/ammonia); the basis of buffer action. (05 Mar 2000) |
