Gene Information

Alteration at locus: Non-mutant

Genetic Alterations:

Genotype Determination:

Parental ES Cell Line: Nagy ES cell line R1 (MMRRC:011978)

Cell line development:
This is a subclone of the bulk R1 ES cell line (MMRRC:011978) and has better developmental potential when tested by tetraploid complement assay and is superior to the R1 ES cell line.
Mouse strain from which the parental cell line was derived: Hybrid of two 129 substrains (129X1/SvJ and 129S1/SV-+p+Tyr-cKitlSl-J/+)

Donor: Andras Nagy, Ph.D., Mt. Sinai Hospital, Toronto

The Donating Investigator reports that this subclone of bulk R1 ES cells exhibits improved developmental potential compared to the standard R1 ES cell line.

Supplemental Information

Requested cell lines are tested by PCR analysis for mycoplasma spp. and Murine Parvoviruses (MPV) upon completion of expansion and prior to shipment. 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

Cryo-preserved ES cell line material can usually be shipped in 2 to 4 weeks.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

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.
