The targeting vector has been generated using 129SvEv DNA and transfected into 129SvEv ES cell line.
Gabra5 exons 2-4 were partially deleted by the neomycin resistance cassette, which is flanked by loxP sites.
Chimeric mice were produced and germ line transmission achieved.
The neomycin resistance gene has not been deleted in the constitutive KO mice.
Deletion of parts of exons 2 and 4 and complete deletion of exon 3 should result in loss of function of the Gabra5 gene by deleting functional domains of the protein.
Gabra5 constitutive KO mice are in a mixed C57BL/6-129SvEv genetic background.
