description
Allele Type:    Targeted (Null/knockout)
Mutation:    Not Specified
 
Mutation detailsThe allele was generated by replacing exon 4 of the Gen1 gene on chromosome 12 with a loxP-flanked neomycin cassette. The construct was electroporated into embryonic stem (ES) cells. The floxed neomycin cassette was removed via transient expression of Cre recombinase. (J:101977, J:330401)
