Image excerpts of representative dual or tri-fluorescence channels time series of PEI, PLGA and DOPC gene carriers with red fluorescence-labeled DNA in Xenopus cytoplasmic extract supplemented with green fluorescence-conjugated actin. PEI polyplexes formed actin clouds but did not display comet-tail motility while both small and large PLGA/DNA particles (0.25 μm and 2.5 μm), and DOPC lipoplexes (with Marina Blue-labeled lipid) were observed to polymerize actin and exhibit actin comet-tail motility.
