- Abstract
The main requirement of a transfection agent has to condense DNA efficiently, protect the DNA from nucleases and other degrading enzymes during its transport in a target cell. In this research, Polysorbate 20 which is commercially known as Tween 20 has been supplemented to oligopeptide-based liposome formulation in order to achieve a stable and effective transfection agent in mediating gene expression. Complex particle size and its stability of transfection agent/DNA were determined by dynamic light scattering analysis. Transfection study was carried out using green fluorescence protein (GFP) encoding gene on HepG2 cells. It was revealed that the addition of Tween 20 (0.5% v/v) on liposome formulation reduced the particle size of the liposome/DNA complexes. The addition of Tween 20 in liposome capable to condense DNA molecules effectively. The particle size of the liposome/DNA at charge ratio 1.0 was ~340 nm; meanwhile, Tween 20 increased the zeta potential value at any charge ratio applied. Interestingly, the inclusion of the Tween 20 has also stabilized the liposome as the particle size almost unchanged after the complexes of the liposome/DNA was monitored for 240 h (10 days). Unfortunately, we did not observe that the addition of Tween 20 in the liposome formulation (0.5% v/v) has beneficial for gene expression as the GFP expression level reduced compared to the corresponding oligopeptide. In summary, Tween 20 (0.5% v/v) addition in the liposome formulation has condensed and stabilized the liposome/DNA complex in nanoparticle size, however, it needs further exploration in formulating Tween 20-containing liposome to achieve optimum beneficial in gene expression.
