Generation of genetically modified mice

Generation of genetically modified mice via CRISPR-Cas technology, random transgenesis and embryonic stem cell targeting
– Constitutive and conditional gene knock-outs and point mutations
– Knock-in tagged genes
– Large complex conditional gene modifications
– Random transgenesis

Identification of correct genome edited alleles

Potential founders (G0) are screened for the targeted modification via PCR, Sanger sequencing, PCR-RFLP and cloning. Positive candidates (most probably mosaics) are bred with wild types and same screening plus long reads sequencing is performed in G1 generation.

Cryopreservation of mouse embryos and gametes

Mouse lines within the unit are cryopreserved during the early stages of colony establishment. This process ensures the preservation of valuable strains, providing protection against potential losses caused by environmental disasters, disease outbreaks, or genetic drift. Additionally, cryopreservation facilitates the sharing of strains within the scientific community.

Import and export of mouse models from and to collaborators outside CRUK MI and repositories

We coordinate communications between facilities, collaborators and couriers, executing rederivations and health screenings.

Assisted reproductive technologies

We specialise in performing in vitro fertilisations for strains experiencing fertility challenges, including age-related issues. Additionally, we can restore mouse lines from frozen gametes or embryos.

Colony management and complex genotyping design

Our team is also available to provide expert guidance on managing mouse colonies and design optimal genotyping assays for complex lines, streamlining the research workflows.

Leukaemia Immunology & Transplantation

The Leukaemia Immunology and Transplantation laboratory aim to develop a comprehensive strategy to prevent post-transplant relapse in patients treated with allogeneic haematopoietic stem cell transplantation – the only curative therapy for many patients with acute myeloid leukaemia (AML) and other poor-risk haematological malignancies.
