Sentences with phrase «own luciferin»

When ATP comes into contact with the liquid - stable luciferase / luciferin reagent in the SystemSure's testing swap, light is emitted in direct proportion to the amount of ATP present.

In his logs Snaith often wanders outrageously off the mark to discuss such things as hairdos at Bennington College, the Roman mile, the Papal Line of Demarcation, the uncommon anatomy of the common raccoon, the use of luciferin in chemiluminescence and the effect of private habits on mores in the reigns of Louis XIV and Louis XV.

Fluorescence of Cypridina oxyluciferin is greatly enhanced when it is bound to luciferase; the spectrum is thereby shifted, so that it corresponds precisely to the emission spectrum characteristic of the bioluminescentoxidation of luciferin.

At the Monterey Bay Aquarium Research Institute, for example, marine biologist Steven Haddock recently discovered that certain jellyfish can not manufacture their own luciferin and that they probably get it from eating small crustaceans.

When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced.

It is generated by an enzyme - catalyzed chemoluminescence reaction, wherein the pigment luciferin is oxidised by the enzyme luciferase.

Most bioluminescent organisms, including fireflies, get their glow from a chemical reaction between the enzyme luciferase and a molecule called luciferin.

One major obstacle to harnessing bioluminescence is that the process relies on a class of compounds called luciferins.

Luciferin molecules react with oxygen incredibly rapidly, burning out almost immediately.

One is called a «luciferin», from the Latin for «light bearer».

Fireflies get their glow through the interaction between an enzyme called luciferase and a molecule called luciferin, so both of these were added.

The luciferin and coenzyme A were packaged inside polymer nanoparticles that enter and build up in an inner layer of the leaf, while the luciferase was contained inside much smaller silica nanoparticles, allowing them to enter the plant cells.

As the luciferin is released from its particles, it too enters the cells and reacts with the luciferase, creating the glowing effect.

Direct injection of plasmids for Antares or firefly luciferase into mouse livers followed by i.v. injection of furimazine or luciferin 24 hours later demonstrated a more than 2-fold brighter signal from Antares as compared to Fluc in this model.

Six days later, the mice were injected with luciferin, imaged with IVIS 50 optical imaging (Xenogen), and randomized into the study groups (6 mice per group) based on bioluminescent tumor burden.

Eight days after inoculation mice were injected intraperitoneally (IP) with 75 mg / kg of D - luciferin in 150 μl PBS and imaged 15 min later under isoflurane anesthesia in a Xenogen IVIS Spectrum.

The source of the bioluminescence is two molecules: luciferase (an enzyme) and luciferin (a molecule produced by photosynthesis).

Researchers believe that the fungi make light in the same way that a firefly does, through a chemical mix of a luciferin compound and a luciferase.

But scientists haven't yet identified the luciferin and luciferase in fungi.
