Correction for Cisse et al., Single-Molecule Chemistry and Biology Special Feature: Fueling protein–DNA interactions inside porous nanocontainers

BIOPHYSICS. For the article “Single-Molecule Chemistry and Biology Special Feature: Fueling protein–DNA interactions inside porous nanocontainers,” by Ibrahim Cisse, Burak Okumus, Chirlmin Joo, and Taekjip Ha, which appeared in issue 31, July 31, 2007, of Proc Natl Acad Sci USA (104:12646–12650; first published June 11, 2007; 10.1073/pnas.0610673104), the authors note that, due to a printer's error, the first sentence of Materials and Methods, on page 12650, appeared incorrectly. “Lipid films were prepared by mixing biotinyl cap phycoerythrin with DMPC dissolved in chloroform (1:100 molar ratio) then vacuumed for 2 h,” should instead read: “Lipid films were prepared by mixing biotinyl cap phosphoethanolamine with DMPC dissolved in chloroform (1:100 molar ratio) then vacuumed for 2 h.” This error does not affect the conclusions of the article.
