Gene Information

Genetic Alterations
High throughput gene trapping was performed by inserting a gene trap vector containing a splice-acceptor sequence upstream of a reporter gene, β-geo (a fusion of β-galactosidase and neomycin phosphotransferase II), into an intronic or coding region of genomic DNA. The resulting insertional mutation creates a fusion transcript containing sequences from exons upstream of the insertion joined to the β-geo marker, allowing cell lines where the vector has successfully interrupted a gene to be identified.

Colony and Husbandry Information

ES Cell Sex and Genotype: These ES Cells are expected to be male (XY) and heterozygous/hemizygous for the mutation.

Requested cell lines are tested by PCR analysis for mycoplasma spp. and Murine Parvoviruses (MPV) upon completion of expansion and prior to shipment. The parental cell line E14Tg2a.4, from which these cells were derived, was tested for multiple mouse pathogens; please see the Health Status Report.

Mice derived from requested cell lines via Microinjection services will be pathogen tested prior to delivery of mice and health reports will be provided. If you require additional health status information prior to requesting microinjection please email

Order Request Information

MMRRC Testing of the BayGenomics, SIGTR, and Soriano gene trap cell lines includes RACE sequencing and mycoplasma and MPV testing. All mutant ES cell lines are heterozygous for the mutation, meaning they carry one modified allele and one wild type allele. MMRRC also recommends performing chromosome counts or karyotyping prior to injection of clones.

Estimated timelines: The repository was sent only one or two vials per clone/cell line from the production center. Processing ES cells (including genetic verification) prior to shipping or injection requires 6-8 weeks. Chromosome counting (to determine % euploid cells) requires an additional 4-8 weeks. Microinjection requires an additional 11-15 weeks. Germline transmission testing (breeding of chimera) requires an additional 8-16 weeks. Germline transmission is not guaranteed.

Please complete the Sanger Institute Gene Trap MTA. This document must be signed by an authorized Technology Transfer representative from your institution. Please provide two signed originals, mailed to the address located on page 2 of the MTA. The MTA will be counter-signed by a designated representative from the MMRRC, and a fully executed copy returned to your institution. Your request will be processed upon receipt of the signed MTA at the appropriate MMRRC center.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.
