Research output: Chapter in Book/Report/Conference proceedingChapter


Despite the advances made in genetic engineering of Saccharomyces cerevisiae, the multicopy genomic integration of large biochemical pathways remains a challenge. Here, we developed a Di-CRISPR (delta integration CRISPR-Cas) platform based on cleavage of the delta sites by Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated systems (Cas) to enable unprecedented high-efficiency, multicopy, markerless integrations of large biochemical pathways into the S. cerevisiae genome. Detailed protocols are provided on the entire workflow which includes pDi-CRISPR plasmid and donor DNA construction, Di-CRISPR-mediated integration and analysis of integration efficiencies and copy numbers through flow cytometry and quantitative polymerase chain reaction (qPCR).
