Mutation description

• Allele Type: Targeted (Null/knockout, Reporter)
• Mutations: Insertion, Intragenic deletion Vector: L1L2_Bact_P
• Mutation details: The L1L2_Bact_P cassette was inserted at position 54692447 of Chromosome 12 upstream of the critical exon(s) (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 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 exon(s) at position 54693720. The critical exon(s) were thus flanked by loxP sites and subsequent cre expression then excised this critical sequence resulting in a reporter knockout allele.
