Strain GQC Summary
Gene Specific Genotyping:

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Suggested Control Mice

Strain Development
Built on V6.5 ESCs (B6129S4F1), chimera crossing to C57BL/6J, and Flp deletion with B6.Cg-Tg(Pgk1-flpo)10Sykr/J (RRID:IMSR_JAX:011065, a B6-congenic with a mix of B6N and B6J with C3H components). Subsequent backcrossing to C57BL/6J.

Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain's tissue samples taken when archived by or ordered from the assigned MMRRC Center.
