This tool is for designing and ordering a single-strand DNA donor (≤ 150 nt) for precise CRISPR-Cas9 gene editing with the HDR pathway.
To design a crRNA to cut near the genomic alteration site of interest, first use the CRISPR Design Tool.
If you already have a guide RNA that is near the desired alteration site, enter the gene information and 20 nt guide RNA target sequence below.
