In vitro luciferase expression of GL261.luc over 21 days. GL261.luc cells were maintained in culture over 21 days. At day 0, 7, 14, and 21, cells were seeded in 6-well plates at a defined density and were evaluated for bioluminescence. GL261 and U87.luc cells were used as negative and positive controls, respectively.
