英文摘要 | Natural Science Foundation of the Jiangsu Province [BK2007232]; Natural Science Foundation of the Fujian Province [2009J01200]; Key projects in the Fujian Province Science and Technology Program [2009D019]; Xiamen Science and Technology Program [3502Z2008; We previously reported the synthesis and characterization of a novel cationic polymer gene vector. The present article further explored and optimized the working conditions of the Sofast gene vector both in vitro and in vivo, and improved its performance. The transfection conditions of Sofast, such as cell type, cell density, transfection time, N/P values and analysis time after transfection, were further explored. Moreover, the effects of the fusion peptide diINF-7 on transfection efficiency were examined. Sofast was successfully applied for the transfection of exogenous genes into more than 40 types of cell lines derived from humans, mice, monkeys and other species. When the cells were 50-80% confluent, Sofast possessed a better transfection efficiency. In most cases, Sofast also had a higher transfection efficiency when it was used to transfect cells that were seeded for several hours and had adhered to the substrate. The results from in vitro experiments indicate that the recommended Sofast to DNA mass ratio is 16:1, and the optimum analysis time after transfection is 48 h. The salt concentration in the Sofast working solution markedly affected the transfection efficiency. When conducting in vivo transfection, the working solution should be salt-free, whereas for in vitro transfection, it is more appropriate for the working solution to include certain salt concentrations. Finally, the results confirm that diINF-7 significantly promotes the transfection efficiency of Sofast. In conclusion, the present research not only established the optimal conditions for Sofast in the transfection of commonly used cells, but also built the foundations for in vivo and in vitro applications of Sofast, as well as its use in clinical practice. |
