of Mice: C
Inbr: 124. Genet: b.
Origin: Strong 1920, from a cross of Bagg
albino female x DBA male. Strains C3H, CBA, CHI and C121 originated from
the same cross.
Moderate mammary tumour incidence.
Inbr. F55 (1993). Genet. A,b,c. Origin: Developed from the 13th. backcross
to BALB/c by Michael
Potter, NIH, to E. Weiler, ICR in 1964. At ICR the mice were backcrossed
to the BALB/cAnNIcr strain for four more generations by Melvin Bosma.
N17 progeny were then intercrossed
to obtain mice homozygous for Ighb
. In 1970 Bosma gave the
mice to the Laboratory Animal Facility at the Institute
for Cancer Research at Fox Chase Cancer Center. The strain is now maintained
in an SPF barrier facility. Its characteristics are essentially those
of BALB/c, and its primary use is as a coisogenic control strain for C.B17/Icr-scid.
