Cellular uptake of GPP-modified polyplex post caveolin-1 silencing. a) Caveolin-1 (cav-1) silencing efficiency was determined 2 days post-treatment via western blots. Expression levels relative to a non-treated control were also examined 1 and 3 days post treatment (Fig. S1). b) Changes in polyplex endocytic pathways mediated by GPP-modification and continued association with collagen fragments were elucidated in caveolin-1 silencing transfection experiments. Each data point represents the mean +/− standard deviation for a total of six separately prepared and analyzed samples.
