• Parent Cell Line: E14 (ES Cell)
• Strain of Origin: 129P2/OlaHsd

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: This allele was generated by breeding mice heterozygous for Cnr1^tm1Ltz with transgenic mice ubiquitously expressing cre recombinase. Southern blot analysis showed that the entire open reading frame was removed, leaving a single loxP site and the FLP-recombinase target (FRT) flanked neo transgene in the single exon at this locus. A lack of transcript was determined via in situ hybridization of homozygous mutant embyros. (J:77936)
