| molecularNote | The L1L2_Bact_P cassette was inserted at position 24558604 of Chromosome 12 upstream of the critical exons 4 and 5 (Build GRCm39). The cassette is composed of an FRT site followed by lacZ sequence and a loxP site. This first loxP site is followed by a neomycin resistance gene under the control of the human beta-actin promoter, SV40 polyA, a second FRT site and a second loxP site. A third loxP site is inserted downstream of the targeted exons 4 and 5 at position 24560225. The critical exons 4 and 5 are thus flanked by loxP sites. Flp-mediated recombination removed the lacZ and neomycin resistance gene. Cre-mediated recombination deleted exons 4 and 5.
