The lanthanide chelate's emission is technically not fluorescence (i.e. arising from a singlet to singlet transition) and has a very long fluorescent half-live (∼ms) compared to the short half-life (∼ns) of most organic fluorophores.
Ducks is purposefully ill lighted, with a few vertical fluorescents (half of them on the blink) and, above the bar, enormous dusty lamps that suggest Pyrex flasks.
Austerely furnished with a single fluorescent light, half-broken chairs and a solitary table scarred with overlapping teacup rings, the room defused all expectations of literary glamour.
While men were able to recall pairs of words flashed across the fluorescent screen about half the time, some scores rose to almost 70 percent when they stared at the LED monitors.
Single host fluorescent device had half-lifetime of 73.5 h only at an initial luminance 100 cd/m2.
Transient transfection of: (1) AKT-IFPN (intensely fluorescent protein amino-terminal half) and RAB25-IFPC (intensely fluorescent protein carboxy-terminal half) or (2) AKT-IFPC and RAB25-IFPN fusion proteins in HEY ovarian cancer cells resulted in fluorescence indicating association of AKT and Rab25 protein in the PCA complex (Fig 5A upper panel, double transfected cell indicated by arrow).
Along the sofa every three and a half feet, fluorescent tubes glow through translucent plastic diffusers.
The distance at which background-subtracted doxorubicin fluorescent intensity decreased to half its original value (L) was greater in HCT-8 Ra and 1R1 xenografts than that in HCT-8Ea and E11 tumours.
The fluorescent molecules were split in half, with one half being implanted in the 'talking' neuron and the other in the 'listening' neuron.
In addition to more than 400 tons of asbestos, this film counts 90,000 tons of jet fuel containing benzene; mercury from more than a half-million fluorescent lights; 200,000 pounds of lead and cadmium from computers; crystalline silica from 420,000 tons of concrete, plasterboard and glass; and perhaps as much as two million pounds of polycyclic aromatic hydrocarbons from the diesel-fueled fires.
Thus, the signal detected by the instrument is contributed only by the fluorescent molecules in one half-sarcomere.
