Bioluminescence imaging in mice with synthetic luciferin analogues.

ABSTRACT

Luciferase enzymes from bioluminescent organisms can be expressed in mice, enabling these rodents to glow when treated with a corresponding luciferin substrate. Light emission occurs where the expression of the genetically-encoded luciferase overlaps with the biodistribution of the administered small molecule luciferin. Here we discuss differences between firefly luciferin analogues for bioluminescence imaging, focusing on transgenic and adeno-associated virus (AAV)-transduced mice.
