Strain descriptions

  • MHC Haplotype RT1lv1
  • The most popular strain of rat for use in carcinogen evaluation
  • Relatively low incidence of naturally occurring neoplasms.
  • High responder to induced neoplasms via chemicals and/or irradiation.
  • Glandular changes associated with the spontaneous interstitial cell tumours of the testis.
  • Resistant to spontaneous autoimmune thyroiditis.
  • Low incidence of nephritis.
  • Good breeding performance.
  • Young females are jumpy and don’t like being handled.
  • Received as Germ Free animals from Charles River Breeding Laboratories, USA (1983).
  • Charles River rederived F68 from NIH in 1960 to SPF status, NIH received as F51 (1950) from Heston. Heston from Columbia University, USA (1949). Originally developed as an inbred by Curtis (1920) at Columbia University Institute for Cancer Research, USA.
