Orange

Kusabira Orange

橙色の蛍光を発し、pH安定性を示します。蛍光スペクトルがシャープであるため、通常組み合わせ難い赤色蛍光タンパク質とのマルチカラー蛍光イメージングが可能です。Keima570、Keima-Red: 前者は橙色(蛍光極大570 nm)、後者は赤色(蛍光極大620 nm)の蛍光を発します。共にストークシフト (励起ピークと蛍光ピークの差) が大きく、蛍光観察時に他色の影響を受けにくいため、マルチカラー蛍光イメージングに適しています。さらにレーザーなどの単波長励起による多波長測定にも適しています。

Keima570 and Keima-Red

Emitting orange light (maximum fluorescence 570 nm, Keima570) and red light (maximum fluorescence 620 nm, Keima-Red), respectively. Both have large Stokes shift.

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.
