Transgenic mice are generated by injecting cloned DNA into zygotes which are then transferred in pseudopregnant females to develop to term. Mouse strains routinely used as zygote donors are FVB/N and C57Bl/6N. Genotyping samples are taken for screening potential founders by PCR or southern blot. A robust screening method must be established before submitting DNA for microinjection. Service includes purification of the DNA construct, microinjection, transfer of 300 embryos and taking genotyping samples.
