CRISPR mutagenesis

Using CRISPR technology, we make null mutations, defined point mutations, epitope and reporter tags, and conditional mutations in mice. We also make null mutations in rats and other species.

Gene targeting in mouse embryonic stem cells

We make genetic modifications in mice using classical gene targeting strategies in embryonic stem cells. This involves the production of chimaeras for obtaining germ line transmission of the genetic modification.

Production of transgenic mice, rats and other species

We make transgenic mice, rats and other species by injecting fertilized eggs with DNA for random integration into the genome. Applications include BAC transgenesis for faithful gene expression, and smaller plasmid constructs for various purposes.

DNA construct design and production

We can design and make your construct for CRISPR mutagenesis, gene targeting in ES cells or transgenic animal production. With our BAC recombineering expertise, there is no limit to the type and range of constructs we can make — quickly and cost effectively.

We use use strain C57BL/6JMarp (B6J) as our standard for producing genetically modified mice. This strain was sourced directly from The Jackson Laboratory (JAX), strain C57BL/6J, JAX stock no. 000664. We last re-stocked from JAX in 2012. Our stock remains within 20 generations of brother-sister mating from the JAX strain to minimize genetic drift and to circumvent substrain formation. At JAX, strain C57BL/6J is included in their Genetic Stability Program to curtail genetic drift. Strain C57BL/6N (B6N) is used in conjunction with embryonic stem cells imported from international repositories. Others strains can be used on request — please enquire.
