Coat Color  Agouti
Inbred Generations  Congenic strain was establiesh using a “speed congenic” strategy as N6F1 in 1999. Subsequently, interval-specific recombinants were bred from an F2 breeding. R25 recombinant was established in 2003. Since then, the strain was kept as inbred.

Origin Inbred Dark Agouti (DA) and Brown Norway (BN) rats were originally obtained from the Zentralinstitut für Versuchstierzucht (Hannover, Germany). Congenic strain was establiesh using a “speed congenic” strategy (Wakeland et al. 1997). Briefly, in each backcross generation, rats for further breeding were selected on the basis of genotyping of 8 microsatellite markers in the congenic region, from marker D9Wox24 to D9Rat20. The genetic background of rats was also screened with 100 markers. After the complete removal of the donor genome outside the congenic fragment, two heterozygous rats were intercrossed to produce the homozygous strains DA.BN-Eae4(N7F1). Subsequently, interval-specific recombinants were bred from an F2 breeding. R25 recombinant was established in 2003.
Strain characteristics Protection against experimental autoimmune encephalomyelitis (EAE) compared to the susceptible parental DA strain, regulation of proinflammatory T cell activation and regulatory T cells.
Breeding Conditions Good breeding performance.
Genotyping Flanking markers inside the congenic fragment: D9Wox24-D9Rat44.
