The Mutant Mouse Resource and Research Centers (MMRRC) is excited to introduce our new Strain Quality Control (SQC) reporting system. This system is designed to make it clearer, faster, and easier for you to assess the accuracy of information available on mouse strains submitted by investigators for distribution from our repositories. Our goal is to be fully transparent about what we know and don’t know regarding MMRRC mouse strains in our catalog. As an MMRRC Center performs additional quality control steps on a mouse strain, its SQC report will be updated as information becomes available.

The new SQC system presents key information clearly in an easy-to-read table format, including:

• Genetic Characterization: Specific genetic makeup (allele-specific genotypes) and background of a mouse strain.
• Viability and Recovery: Survival rates and breeding potential of mutant mouse strains, and whether strains can be reliably frozen and stored as sperm or embryos.
• Health and Performance: Overall health, pathogen status, fertility, and breeding effectiveness.
• Functional Insights: Availability of gene sequences, gene expression and function, and any observed physical or behavioral traits.

How to View an SQC Report:
To view an example of a completed SQC table, please see the SDS page for C57BL/6-Clptm1tm1a(KOMP)Wtsi/AmcrMmjax.
