Publisher Correction: Lung and liver editing by lipid nanoparticle delivery of a stable CRISPR–Cas9 ribonucleoprotein

In the version of the article initially published, in the “Directed evolution of GeoCas9” section of the Methods, the text “After recovery of the electroporated bacteria in 750 µl of sulfur-oxidizing bacteria for 1.5 h at 30 °C” should have read “After recovery of the electroporated bacteria in 750 µl of SOB medium (Super Optimal Broth) for 1.5 h at 30 °C.” This correction has been made to the HTML and PDF versions of the article.
