Mutation description

• Allele Type: Targeted (Conditional ready, Modified regulatory region, No functional change)
• Mutation: Insertion
• Mutation details: The differentially methylated region (DMR), located upstream of the H19 transcription initiation site, was left flanked by single loxP sites at -6.5 to -0.8 kb upstream of H19 major start within the regulatory region 27 (Rr27) and a neomycin-resistance gene flanked by loxP sites inserted at the -7.0kb upstream of H19. The neo-cassette was removed in ES cells by transiently transfecting with a Cre recombinase-expressing plasmid. (J:82798)
