Good remark but we were thinking of luciferase outside the cellular context. Keeping cells alive is a very big challenge. But arguable keeping “naked” luciferase functional is as well… For cells you need a lot more than just glucose, you needs some medium and fetal bovine serum and you need a way to remove waste and dead cells, etc.
