The first, third, and fourth Ctcf target sites within the imprinting control region (ICR) were modified from GTGG to ATAT via site directed mutagenesis. A floxed neomycin resistance gene cassette that was included in the targeting vector for selection was excised via in vivo cre-mediated recombination in the germline. (J:82427)
