Fig. (2) Basal activity of the LANAp and its deletion mutants in MV3 cells (black bars) and BC-3 cells (white bars). Luciferase expression was measured after transfection of the cells with the indicated luciferase reporter constructs. MV3 cells were electroporated with 1 µg of reporter gene plasmid; BC-3 cells were electroporated with 10 µg of reporter gene plasmid. Relative luciferase activity is depicted. Data represent three independent experiments with transfection efficiency being 55 ± 15 (MV3) and 60 ± 10 (BC-3) %, respectively.
