Description of our model

These F1 hybrids are the result of a cross between a C57BL/6JRj female and a SJL/JRj male. F1 hybrids are heterozygous at every locus (provided that the parental strains have different alleles).
As is the case with inbred strains, they are genetically and phenotypically uniform.

F1 hybrids are often used for their hybrid vigour (resistance and acitivity). They are especially interesting as genetic background (vigour and repeatability of genetic inheritance) for harmful phenotype models, for tissue transplantation, to determine mechanisms of inheritance, to create or improve expression of polygenic disease.

It is also used in behavioural studies, radiation, safety and efficacy testing for nutrients, medicine, pathogens or hormones.

Our added value

  • The « JANVIER LABS Genetic Policy », a specific programme, guarantees the genetic repeatability of our hybrid models.
  • Animals with the SPF or SOPF standards.
  • A gentling policy for docile and easy-to-handle animals.
  • Optimal stability conditions of our models during shipments, thanks to our dedicated and internal transport service.
  • A scientific support with a team of Veterinarians and PhD.
