Figure 4From: Design and characterization of a new peptide vector for short interfering RNA delivery a SEM image of GL1-siRNA complexes at molar ratio 40/1, siRNA concentration was 100 nM. b CD spectra of GL1 alone and GL1-siRNA at different molar ratios. GL1 concentration was fixed at 30 μM and GL1-siRNA complexes were formulated at molar ratios of 5/1 and 10/1.Back to article page
