Luciferase Assay from Promega

I am using the scintillation counter for this type of assays.  It works
fine.  The problem is how to convert the readings in cpm to the lumino-
unit, or just get the square root of the reading and give it an arbitrary
unit.

One thing to make clear, I use the bacterial luciferase and do the assay
in vivo by supplying the c12-aldehyde.

Hope this helps.
