Model Creation with Charles River

Charles River Europe has joined forces with PHENOMIN-ICS, a scientific leader in functional genomics, to deliver a complete solution for mouse and rat model creation. Our combined in vitro and in vivo expertise provides an optimal environment for creating, validating, characterizing, preserving and distributing your transgenic and mutant rodent lines. PHENOMIN-ICS is considered a gold standard for successful germline transmission by the IMPC.

  • Genotyping

    PHENOMIN-ICS has more than 10 years of experience in providing robust, accurate, and fast results.

    • Genotype your transgenic line by a customized protocol PCR or qPCR on complex alleles or multiple regions of a locus for more in depth validation of a mutant model
    • Genotype your cohort by a high throughput protocol. Simplified genotyping with one qPCR on specific region to minimize costs for established and verified lines
    • Genotype your cryopreserved line (blastocysts and sperm genotyping)
  • Phenotyping

    Systemic phenotyping of mutant mice is crucial in order to understand the relations between genotype, phenotype and environment. With a comprehensive panel of phenotyping tests, we provide standardized and customized protocols. We have developed a battery of tests to address most of the biological functions and cover the main therapeutic areas:

    • Neurobiology and behavior platform: analysis of sensory responses, motor abilities, cognitive functions as well as behaviors related to neuropsychiatric disorders, such as anxiety, depression or schizophrenia. 
    • Metabolic exploration platform: detection of phenotypes in energy metabolism, glucose homeostasis, bone metabolism, renal and intestinal function.
    • Cardiovascular platform: detection of congenital heart disease, myocardial infarction, valve disease, cardiac hypertrophy, arrhythmias, hypertension and hypotension.
    • Oncology: various of engraftment, monitoring of tumor progression by in vivo imaging Clinical Chemistry platform: blood and urine analysis (clinical chemistry, hematology, immunology, endocrinology).
    • Histopathology and embryology: histopathological analyses of adult tissues and mouse developmental biology
