Correction to: Nature Communications https://doi.org/10.1038/s41467-020-18615-1, published online 30 September 2020.

In the original version of this Article, the composition of buffer D in the “Methods” section “LbCas12a expression and purification” was incorrectly provided as “(100 mM NaCl, 20 mM HEPES, 0.5 mM TCEP, pH = 8)”. It should have read “(2 M NaCl, 20 mM HEPES, 0.5 mM TCEP, pH = 8)”.

This has been corrected in both the PDF and HTML versions of this Article.
