Retraction of ‘A multifunctional self-dissociative polyethyleneimine derivative coating polymer for enhancing the gene transfection efficiency of DNA/polyethyleneimine polyplexes in vitro and in vivo’ by Cheng Wang, et al., Polym. Chem., 2015, 6, 780–796.
In Fig. 7a, two of the panels contain incorrect images. The picture of HeLa-DPFPH was part of the result of HeLa-DPLPHF, and the result of A549-DPLPHF was from other experiments. The authors report that this was due to a computer shutdown during the experiment, which caused errors in the naming of the files and therefore, when Fig. 7a was prepared, pictures from incorrect experiments were used to represent the results of other experiments.
In addition, Fig. S2 and Fig. 3B also shared the same background. The authors explain that, owing to a lack of goldview, a DNA indicator, the experiments were performed on the same gel after the preliminary sample had been electrophoresized.
Since these mistakes might influence the scientific validity of the article, the authors retract this paper to protect the accuracy of the scientific record.
