Technical Officer - Transgenic Mouse Service / Microinjection

Technical Officer - Transgenic Mouse Service / Microinjection

European Molecular Biology Laboratory (EMBL)

Heidelberg, Germany


About the team/job


Our Laboratory Animal Resources (LAR) consists of several organisational units providing service to EMBL investigators. The Transgenic Service facility provides a wide scope of complex techniques to EMBL researchers to mainly support the generation of genetically modified mice. The Transgenic Mouse Service directly reports to the Scientific Head of LAR.


Your role


You will be part of a small-scale, high-standard service facility generating genetically modified mouse lines for EMBL research groups. You will be expected to organize and conduct all daily procedures related to transgenic and knock-in/knock-out mouse production.

Tasks include:



  • Microinjection of DNA (including large constructs), CRISPR/Cas9 approaches, generation of chimera from targeted ES cells by injection into morula and blastocyst stages.

  • Organisation and supervision of breeding colonies of wild-type and mutant mice necessary for the work of the transgenic service under standard operating procedures.

  • Cryopreservation of mouse stocks (embryo, sperm freezing).

  • Rederivation of in-coming mouse lines into a SPF barrier facility (IVF, embryo transfer).

  • Use of intracytoplasmic sperm injection (ICSI).

  • Maintenance and updating of the online transgenic database for tracking work at the facility.

  • Establishment and coordination of training activities both internal and external to EMBL in the area of transgenesis.

You have


As our ideal candidate, you should either be a trained technician or have an equivalent education and experience in working with mice and in the generation of genetically modified mice. An extensive and successful hands-on experience in ES cell culture and injection, pronuclear injection of DNA and embryo/sperm cryopreservation is essential. You should be able to work both independently and in close collaboration with the scientists and technicians associated with the transgenic projects. You should be highly motivated and have good communication, project management and organizational skills. English being the working language, good written and spoken command is essential.
