Aminoluciferins as functional bioluminogenic substrates of firefly luciferase.
Firefly luciferase is widely used as a reporter gene in assays to study gene expression, gene delivery, and so on because of its extremely high signal-to-noise ratio. The availability of a range of bioluminogenic substrates would greatly extend the applicability of the luciferin-luciferase system. Herein, we describe a design concept for functional bioluminogenic substrates based on the aminolu...
متن کاملSimple and Rapid Immobilization of Firefly Luciferase on Functionalized Magnetic Nanoparticles; a Try to Improve Kinetic Properties and Stability
We expressed and purified a recombinant P. pyralis luciferase with N-terminal His-tags. The silanized Ni or Cu-loaded magnetic particles were prepared and used to assemble the His-tagged P. pyralis luciferase. This enzyme immobilized on functionalized magnetic nanoparticles (MNPs) via electrostatic interactions of His-tag with Ni2+/Cu2+ ions on the surface of MNPs using si...
متن کاملDevelopment of a thermostable firefly luciferase
Firefly luciferase forms the basis of a wide range of analytical techniques. However, the enzyme is unstable and rapidly loses activity even at room temperature. This leads to losses in sensitivity and precision in analytical applications and also severely limits the fieldability of devices incorporating luciferase-based technologies. A number of point mutations have previously been identified ...

متن کاملRapid in vivo assessment of drug efficacy against Mycobacterium tuberculosis using an improved firefly luciferase
OBJECTIVES In vivo experimentation is costly and time-consuming, and presents a major bottleneck in anti-tuberculosis drug development. Conventional methods rely on the enumeration of bacterial colonies, and it can take up to 4 weeks for Mycobacterium tuberculosis to grow on agar plates. Light produced by recombinant bacteria expressing luciferase enzymes can be used as a marker of bacterial lo...
