Notes: Beetle Luciferin was used to look at E2F-responsive luciferase expression in a U2OS cell system. A synthetic 6xE2F-Luc reporter was microinjected into the nuclei of the cells. Twenty-four hours later, 1mM beetle luciferin was added to the medium, and emitted photons were acquired using a CCD camera. (2143)
