Characterization of HNB-LCD for the expansion of the short-interfering RNA (siRNA) delivery therapeutic window. (a) Varying amounts of HNB-LCD were added to A431 cells treated with 100 nmol/l E6N2/siRNA-Alexa 488 complexes for 6 hours. siRNA uptake was normalized to uptake by E6N2/siRNA-Alexa 488 in the absence of HNB-LCD (data shown as mean ± SD, n = 6). (b) The therapeutic window for D-PFO was determined for A431-d2EGFP cells in the presence of 7.5 nmol/l HNB-LCD and 100 nmol/l E6N2/siRNA complexes (data shown as mean ± SD, n = 9). (c) The potency of E6N2/siGFP is measured in a GFP knockdown assay in the presence of 100 pmol/l D-PFO and 7.5 nmol/l HNB-LCD (data shown as mean ± SD, n = 9). Cell viability and GFP expression are normalized as in Figure 3.
