Luminescent protein

  • Nano-lantern luminescent and fluorescent protein
    • Nano lantern (NL) consists of Renilla luciferase and adjacent fluorescence protein. The chemiluminescence of the luciferase provides light source for excitation and enables the fluorescence protein to be observed. Three colors of NLs, yellow, cyan and orange, have been developed. NLs do not require external light source and overcome problems such as autofluorescence, phototoxicity, and photobleaching.
  • Higher intensity luciferases having Green-, Yellow- or Red-emission by using D-luciferin
    • These luciferases have at most four-time maximum luminous intensity than that of widely used luciferase of the Photinus pyralis, a common North American firefly. Further more, Green-, Yellow- or Red-emission can be obtained by using D-luciferin as a substrate of each luciferase.
  • AkaLuc luciferase providing brighter and red-shifted luminescence
    • The artificial bioluminescence system AkaBLI enables noninvasive signal observation in deep tissue of living animals. It was developed by Dr. Atsushi Miyawaki and Dr. Satoshi Iwano of the RIKEN Center for Brain Science, and Dr. Shojiro Maki of the University of Electro-Communications. The AkaBLI consists of an artificial substrate AkaLumine with improved tissue permeability and an artificial luciferase Akaluc optimized to AkaLumine. The intensity of the luminescence of AkaBLI system is 100 to 1000 folds brighter than the conventional systems.
