Correction to: Gene Therapy (2006) 13, 400–411. doi:10.1038/sj.gt.3302673

In the Materials and methods section, the paper states erroneously that an amount of 0.51 μmol cationic lipid was used for the preparation of virosomes from 1.5 μmol viral phospholipid. The correct amount is 0.77 μmol cationic lipid corresponding to 34 mol% in the final lipid mixture. The mistake affects the charge ratios given in Figure 1 and in the Results and Discussion sections. The correct charge ratios are 0.91, 2.32, 3.20, and 4.24 for virosomes prepared with 10, 22, 28, and 34 mol% cationic lipids, respectively. The mistake has, however, no effect on any of the conclusions of the paper.

The authors would like to apologise for this mistake.
