Figure 4.

Basal level of expression of cm2 reporter gene constructs in SN56 cells. Basal level of expression of cm2 reporter gene constructs transfected into the mouse septal/neuroblastoma cell line SN56. Levels of luciferase expression normalized to β-gal expression (see Materials and Methods) are shown as fold increase over reporter gene vector (pGL3-Basic) containing no promoter. Results are averages ± SEM from four to five separate experiments each with three to six replicate cultures.
