Figure 2From: Acetylation of PAMAM dendrimers for cellular delivery of siRNAEffect of amine acetylation on siRNA complexation by PicoGreen dye exclusion. Complexes were prepared in PBS at a final siRNA concentration of 2 μg/mL. PicoGreen fluorescence correlates to unbound siRNA present in solution. Data represent mean ± SEM (n = 3).Back to article page
