Transfection Efficiency of FITC-SRCRP2-11-Cy3-siRNA Complexes in MCF7 Cells

FITC fluorescence (gray) and Cy3 fluorescence (black) was measured after 24-hr culturing of the cells in the presence of either FITC-SRCRP2-11-Cy3-siRNA (A) or FITC-SRCRP2-11R-Cy3-siRNA (B) complexes. The amount of FITC-peptides was increased and the amount of Cy3-siRNA was kept constant. Values are the average of three experiments; bars are SEM. Asterisks indicate the significance level, based on the Student’s t test (*p = 0.0021–0.04332, **p = 0.0002–0.0021, ***p = 0.0001–0.0002, ****p < 0.0001).
