Lag3 - Model 14065 - cKO

• The targeting vector has been generated using C57BL/6J DNA and transfected into TaconicArtemis C57BL/6NTac ES cell line.
• Exon 1 contains the translation initiation codon.
• Exon 3 has been flanked by loxP sites (size of loxP-flanked region is 0.8 kb).
• The positive selection marker (Puromycin resistance - PuroR) has been flanked by FRT sites and inserted into intron 3. The conditional KO allele has been generated after Flp-mediated recombination by crossing chimeras to a Flp-Deleter on a C57BL/6 background.
• The conditional KO line has been derived using C57BL/6NTac animals and the Flp-transgene was removed by segregation.
• The constitutive KO allele can be generated by Cre-mediated recombination.
• Deletion of exon 3 should result in the loss of function of the Lag3 gene by deleting part of the extracellular domain and by generating a frameshift from exon 2 to exons 4 to 8 (premature Stop codon in exon 4). In addition the resulting transcript may be a target for Non-sense Mediated RNA Decay and may therefore not be expressed at significant level.
• The remaining recombination sites will be located in non-conserved regions of the genome.
• Datamining and Design performed 2014.

GEM Collection models exist as cryopreserved materials. Models can typically be recovered and delivered to customers within 14-16 weeks after order receipt. Customers will receive:

• A minimum of four (4) mice mutant for the selected mutation. In rare cases where the cryopreserved material also contains a recombinase gene, this may be reduced to 1-2 mutant mice.
• Validated genotyping protocols
• Animal health report. Mice will meet Taconic's Murine Pathogen Free™ (MPF™) health standard.

Please note that in rare instances (2%) cryorecovery may prove to be difficult, either extending timeline or ultimately successful recovery.
