luciferase

In fact, the luciferase activity was reduced almost to background levels with the Ymut1 mutation.

Other commonly used reporters include green fluorescent protein and luciferase.

Luciferase can be produced in the lab through genetic engineering for a number of purposes.

As a control, incubation with a 35S-methionine-labeled luciferase protein failed to show any interaction.

But when it dies, the luciferase gene becomes inactive and the light goes out.

Particle bombardment produced the highest mean levels of luciferase activity (Table 1).

Then the virus, modified with Renilla luciferase, is introduced in the culture.

Luciferase can be used in blood banks to determine if red blood cells are starting to break down.

The injected skin was removed at necropsy and tested for luciferase activity.

This luciferase reaction has a peak wavelength of about 490 nm.

The opportunities for using luciferase continue to expand.

"One way you can do it is to clone the luciferase gene into the yeast that makes champagne," he said.

The renilla luciferase was used as an internal control in addition to untreated mice.

As the protons hit, they create an electrical signal that can be read out just like the burst of light from luciferase is.

So the firefly gene produces more of an enzyme called luciferase during the morning than the evening.

This process has been performed using firefly luciferase gene to produce glowing plants.

Fireflies light up by blending two chemicals, luciferin and luciferase.

They hadn't dared activate the kelp's luciferase, it would make tracking too easy.

They use the term luciferase to describe the enzyme that drives, or catalyzes, the reaction.

Gaussia princeps is used in the production of luciferase.

Such differences are likely due to pH changes or differences in primary structure of the luciferase.

Photinus pyralis is famous in biotechnology for its luciferase gene.

Also well studied is the luciferase from Renilla reniformis.

This shows that luciferase can differentiate between the isomers of the luciferin structure.

At low cell concentrations, V. fischeri did not express the luciferase gene.
