| molecularNote | A loxP site was inserted downstream of CTCF-binding site C15 in the IA/IE-SE super enhancer between H2-Eb1 and H2-Aa, and a second loxP site and an FRT site flanked neomycin resistance gene cassette upstream. The C15 sequence and neo cassette were deleted through subsequent cre-mediated recombination. |
