What's the difference between florescence and fluorescence?
Florescence
Definition:
(n.) A bursting into flower; a blossoming.
Example Sentences:

(11) In 146 patients the acuity of vision, pupil reactions, the oculomotor function of the nerves, visual fields and ocular fundus were examined, employing florescent angiography in some cases: and in 164 patients the state of the acoustic and vestibular analyzers was studied.
(12) Rabbit anti-MOLT and SOMMER-T sera after absorption with liver and B cell showed florescent ring formation in baboon and stumptail lymphocytes by using immunoflurescence techniques.
(13) Intracellular microelectrodes filled with either Lucifer Yellow CH, a highly florescent dye, or horseradish peroxidase (HRP) were used to electrophysiologically characterize and mark cells in the cerebral cortex of cat.
Fluorescence
Definition:
(n.) That property which some transparent bodies have of producing at their surface, or within their substance, light different in color from the mass of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it. The light emitted by fluorescent substances is in general of lower refrangibility than the incident light.
Example Sentences:
(1) The assembly reaction is accompanied by characteristic changes in fluorescence emission and dichroic absorption.
(2) Such an increase in antibody binding occurred simultaneously with an increase in the fluidity of surface lipid regions, as monitored by fluorescence depolarization of 1-(trimethylammoniophenyl)-6-phenyl-1,3,5-hexatriene.
(3) The dependence of fluorescence polarization of stained nerve fibres on the angle between the fibre axis and electrical vector of exciting light (azimuth characteristics) has been considered.
(4) The sensitivity of an indirect fluorescent antibody (IFA) test (screening test) for the detection of antibodies to cytomegalovirus (CMV) was examined by using 128 serum specimens and quaternary aminoethyl (QAE)-Sephadex A50 column chromatography to separate IgM from IgG class antibodies.
(5) Absorbance or fluorescence measurements may be used for detection.
(6) In the present study, 125 oesophageal biopsies obtained under direct vision at endoscopy from 22 patients with Barrett's oesophagus were systematically studied using fluorescence and peroxidase antiperoxidase single and double-staining immunocytochemical methods employing highly specific antibodies to localize the following peptide-containing cell types in Barrett's mucosa: gastrin, somatostatin, gastric inhibitory polypeptide, motilin, neurotensin and pancreatic glucagon.
(7) Likewise, they had little or no effects on the fluorescence anisotropy of TMA-DPH, which is also thought to be located in the interfacial region of the lipid bilayer, either when the probe was located in the outer layer of the plasma membrane or when the probe was located in the inner membrane compartment.
(8) Furthermore, experiments with the fluorescence-activated cell sorter revealed increased forward light scatter from resting exudate PMN compared to blood PMN.
(9) Sulphuric acid fluorescence is used for quantitation and specificity is achieved by the addition of tritiated oestrone to the urine hydrolysate.
(10) At the light-microscopic level, adrenergic fibres were identified due to their formaldehyde-induced fluorescence.

(14) Vital staining of neuroblastoma cells with acridine orange produces a bright intracellular red-orange fluorescence most probably due to the occurrence of RNA.
