The CETP mouse was developed in the laboratory of Dr. David Grass at Xenogen Biosciences, now Taconic. The model was created by microinjecting the human CETP gene into (C57BL/6J x SJL) F2 zygotes. Taconic received stock in April 1996 at the second backcross from the founder line. The mice were then backcrossed one generation to C57BL/6 prior to intercrossing for homozygosity. Backcrossing to C57BL/6NTac recommenced at Taconic in 2004. The line was backcrossed a total of 10 generations (N10) and then intercrossed to homozygosity. A homozygous colony is maintained for the production of hemizygotes through mating to C57BL/6NTac (N11).
