The pHD-Stinger-attP vector is designed for generating dsDNA donor plasmids for CRISPR/Cas9-mediated homology-directed repair (HDR). It was derived from pHD-DsRed-attP by replacing the marker, and contains a Avic\GFPEGFP.3xP3.Tag:NLS(tra) marker flanked by loxP sites (allowing subsequent removal of this marker from a targeted locus), a single attP site and two multiple cloning sites for insertion of 5' and 3' homology arms of the genome region to be targeted. The presence of the attP site allows for subsequent access to a targeted locus.
