molecularNote | The L1L2_Bact_P cassette was inserted at position 60937222 of Chromosome 6 upstream of the critical exon 3 (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 exon 3 at position 60938096. Exon 3 is thus flanked by loxP sites. A null/knockout allele was created by flp and cre recombinase expression in mice carrying this allele to remove the lacZ sequence, neo selection cassette and the loxP-flanked critical exon. Western blot analysis of platelet lysates confirmed the complete absence of protein in platelets from homozygous mutant mice.
