We have generated a single-copy knock-in loci for defined gene expression (SKI LODGE) system to insert any DNA by CRISPR/Cas9 at defined safe harbors in the C. elegans genome. Utilizing a single crRNA guide, which also acts as a Co-CRISPR enrichment marker, any DNA sequence can be introduced as a single copy, regulated by different tissue-specific promoters. The SKI LODGE system provides a fast, economical and effective approach for generating single-copy ectopic transgenes in C. elegans.
