Figure 4

Inhibition of the transfection efficiency at high concentration of serum. Selected complexes (DOTAP-high, DOTAP-low, DC-high, DC-low) were incubated without serum for two hours (normal) or with two volumes of serum for the indicated time prior to transfection of 293A cells and subsequent determination of luciferase activity in the cell extracts. The mean of triplicates and the standard deviation are given as relative light units (RLU) per μg cell extract.
