firefly luciferase is what most people think of in the euk work because
it is a single gene product. However you need to break the cells open
to get in  the substrate.

Bacterial luciferase has 2 subunits and therefore is tricky to express
in eucaryotes. However a number of groups have made gene fusios
fusions of the two subunits, and these work in both proks and euks.
Decanol will diffuse in without requireing cell lysis and hence this
can be used in vivo. But for use in mammalian cells see
Pazzagli et al 1992 Analytical Biochemistry 204:315-323.
