Background strain
Strain developmentFrom Tak. W. Mak of ontario Cancer Institute, N6
Strain descriptionOriginal line was established by Tak Mak at Ontario Cancer Institute in Tronto (Schmits et al., J. Exp. Med., 183, 1415, 1996). Neo registance gene construct was introduced into the CD11a allele of an ES cell line E14k of 129/Ola origin. Mutant ES cells were injected to C57BL/6 blastocysts. Chimeras were mated with C57BL/6 and was backcrossed to C57BL/6 for 6 generations. After embryo transfer at Taconic, the colony has been maintained through intercrossing of homozygous mice.
