I have assayed various constructs from E.coli containing promoters for
human genes. Using SV40 or the human promoter i get very high luciferase
activity (higher than any transfection). I harvest 1.5ml of an overnight
culture and lyse this in 600ul. Then perform the promega lucif. assay and
it is screaming.
