| molecularNote | A loxP site flanked neomycin resistance gene cassette replaced the 46 bp E-box GATA motif (CATCTGCAGCCGGTAGATAA; WGATAR) at the +9.5 kb Gata2 enhancer site in intron 4. Cre-mediated recombination removed the neo cassette. RT-PCR confirmed reduced transcript expression in the liver. |
