The Brightest, Red-Shifted Luciferase-Luciferin Bioluminescent Pairs

Researchers at the University of California, Riverside, have developed several new luciferase-luciferin pairs that have superior brightness and excellent performance in vitro and in vivo. Through directed evolution of the existing NanoLuc Luciferase and the use of diphenylterazine (DTZ) as a substrate, the emission extensity is more than doubled compared to NanoLuc-furimazine. Moreover, red-shifted emission of teLuc-DTZ makes it an excellent tool for in vivo imaging. teLuc-DTZ streamlines a variety of applications to afford high sensitivity and reproducibility. Furthermore, fusing teLuc to a fluorescent protein creates the Antares2-DTZ pair, with emissions further red-shifted to the > 600 nm range and 65 times more photons emitted above 600 nm than FLuc-D-Luciferin. Fig. 1 shows the relative emission intensity and the range of emitted wavelengths of light
