Effect of Tween 80 on particle size and transfection during rehydration. Lipoplexes were formulated in sucrose (sucrose/DNA=2000) and either (A) lyophilized in the absence of surfactant and rehydrated with water, (B) lyophilized in the absence of surfactant and rehydrated with 40 μM Tween 80, or (C) lyophilized and rehydrated in the presence of 40 μM Tween 80. DNA concentration was at 1 μg/ml. Each bar represents the mean ± one standard error of replicates (n ≥ 4). The asterisks indicate transfection rates and particle sizes that are not significantly different from fresh controls.
