fluorescent

 [floo͡-res´ent]
pertaining to or characterized by fluorescence.
fluorescent antibody test a test for the distribution of cells expressing a specific protein by binding antibody specific for the protein and detecting complexes by fluorescent labeling of the antibody. Called also FAB test.
fluorescent treponemal antibody absorption test the standard treponemal antigen test for syphilis: Nonspecific antibodies are removed from patient serum, which is then reacted with Treponema pallidum fixed to a glass slide. Specific antibodies adhering to the treponemes are demonstrated with fluorescein-labeled antihuman globulin. Positive tests are seen in about 85 per cent of cases of primary syphilis, 100 per cent in secondary syphilis, and 98 per cent in late syphilis. The test remains positive for life even after syphilis has been successfully treated. Called also FTA-ABS test.

fluor·es·cent

(flōr-es'ent),
Possessing the quality of fluorescence.

fluorescent

(flo͝o-rĕs′ənt, flô-, flō-)
adj.
1.
a. Of or relating to fluorescence.
b. Exhibiting or produced by fluorescence: fluorescent corals; fluorescent light.
2. Glowing as if with fluorescence; vivid: bright fluorescent colors.
3. Of or relating to a light bulb that produces visible light by fluorescence, especially a glass tube whose inner wall is coated with a material that fluoresces when an electrical current causes a vapor within the tube to discharge photons.
n.
1. A fluorescent light bulb.
2. A lamp that is fitted with a fluorescent light bulb.

Since fluorescent dye molecules with orientations most closely aligned with the laser light's polarization will appear brightest, measuring the brightness of each molecule in each camera frame allowed the researchers to quantify orientation and rotational dynamics on a molecule-by-molecule basis.
Thus, the novel precursor of fluorescent dye PFD has been successfully tested with various cell cultures.
The commonly used fluorescent dyes to detect mitochondria activity include Rhodamine 123 (R123), Mitotracker Green TM (17), Mitotracker Red CMXROs, Mitotracker Deep Red 633 (M-22426) (18), Mitotracker Orange TM (19), DiO[D.sub.6](3) and JC-1 (20).
The intensity of each module can be adjusted independently, precisely and reproducibly in percentage steps, so that for every fluorescent dye, the output emitted is precisely that which is needed to achieve the best possible compromise between the required excitation intensity and maximum sample protection.
We believe that the fluorescent dye injections and single-anchor long-T-bar tagging methods in our investigation will likely prove effective for a longer-term study with additional preliminary tagging analysis.
A new method uses a confocal laser scanning microscope (CLSM) to image the coating layer after it is stained with a fluorescent dye. Rhodamine B is used as the dye because of its fluorescence at the excitation wavelength of 514 nm.
Finally, a second antibody, called a reporter antibody and labeled with a fluorescent dye or a fluorescent quantum dot, binds to a different region on the toxin or pathogen.
They incubated the tissue for 90 minutes in a solution containing musk compounds and the fluorescent dye rhodamine B.
Recently, we have been working with the fluorescent dye, calcein, which is known to coordinate transition-metal ions such as Cu(II) and Ni(II), leading to formation of non-fluorescent complexes.
Liposomes were prepared by the injection method described [27] in previous publications and encapsulated 100 mmol [L.sup.-1] of the fluorescent dye, 5-(and -6) carboxyfluorescein (CF) (Molecular Probes, Eugene OR).
Carbon dioxide diffuses across a semi-permeable membrane of the sensor and into a fluorescent dye solution.
