Firefly luciferases
WebSep 22, 2024 · Luciferases make up a class of oxidative enzymes found in several species that enable the organisms that express them to “bioluminesce,” or emit light. The most famous one of these enzymes is … A variety of organisms regulate their light production using different luciferases in a variety of light-emitting reactions. The majority of studied luciferases have been found in animals, including fireflies, and many marine animals such as copepods, jellyfish, and the sea pansy. However, luciferases have been studied in luminous fungi, like the Jack-O-Lantern mushroom, as well as examples in other kingdoms including bioluminescent bacteria, and dinoflagellates.

AkaLuc: A modified firefly luciferase engineered to use the red-shifted substrate Akalumine with significantly brighter signal and emission in the near-infrared range, enabling enhanced bioluminescence imaging in vivo.; Luciferases with tunable wavelengths: NanoLuc® with either SNAP‐tag or HaloTag7 tag in which labeling …
WebLuciferase. Luciferases comprise a group of enzymes that emit light in the presence of oxygen and a substrate (luciferin). Such a luciferin–luciferase system is found in nature, for example, in bacteria (Vibrio harveyi ), dinoflagellates ( Gonycaulax ), and the firefly ( Photinus pyralis ). These luciferases, in particular the eukaryotic ... WebLuciferases likely evolved at multiple stages during the course of history to yield enzymes that differ in expression pattern, substrate specificity, cofactor requirement and enzyme kinetics. ... Spectral Resolution between different luciferases. Note: Emission of Red Firefly shifted to the right allowing for multiplexing with other luciferases ...
WebIntroduction: A novel, red-shifted bioluminescence imaging (BLI) system called AkaBLI has been recently developed for cell tracking in preclinical models and to date, limited data is available on how it performs in relation to existing systems. Purpose: To systematically compare the performance of AkaBLI and the standard Firefly luciferase (FLuc) systems … WebApr 11, 2024 · Moreover, the firefly luciferase (Fluc) as the bioluminescent reporter has been widely used in life science research and high-throughput screening (HTS). However, Fluc might suffer from direct inhibition by HTS compds. resulting in the occurrence of "false positives." In the current research, we discovered a series of chalcone compds. as Fluc ...
