Correction: Increasing the bactofection capacity of a mammalian expression vector by removal of the f1 ori

This Article was originally published with one of the panels in Figure 5A inserted twice (SL-pEGFP). In Figure 5B there was also a typo. SL-LacZ should have read SL-pEGFP(-f1). Both 5A and 5B are corrected in both the PDF and HTML versions of the Article.
