The International Knockout Mouse Consortium (IKMC) has produced a genome-wide collection of 15,000 isogenic targeting vectors for conditional mutagenesis in C57BL/6N mice. Although most of the vectors have been used successfully in murine embryonic stem (ES) cells, there remain a set of nearly two thousand genes that have failed to target even after several attempts. Recent attention has turned to the use of new genome editing technology for the generation of mutant alleles in mice. Here, we demonstrate how Cas9-assisted targeting can be combined with the IKMC targeting vector resource to generate conditional alleles in genes that have previously eluded targeting using conventional methods.

Embryonic stem cell distribution unit that distributes material arising within European Conditional Mouse Mutagenesis Program consortium, currently targeting vectors and ES cells. Upon user request EUCOMM grow targeting vectors from glycerol stocks and prepare vector DNA. Identity of vector is verified by restriction mapping. Upon user request EUCOMM thaw, expand and re-freeze several aliquots of desired ES cell clone. Standard controls include PCR based assay. Upon additional request EuMMCR unit develops genotyping PCR, which can be used to genotype chimeric mice that may be generated using those ES cell clones.
