Germline Transmission:  Earliest citation of germline transmission: J:86465
Parent Cell Line:  Lex-1 (ES Cell)
Strain of Origin:  129S5/SvEvBrd
Allele Type:    Targeted (Conditional ready, No functional change)
Mutation:    Insertion
Mutation detailsThe coding region of exon 1 was flanked by single loxP sites in the 5' untranslated region of exon 1 and in intron 1. The targeting vector contained a frt-flanked neomycin cassette in intron 1, though this selection cassette was removed via in vivo FLP-mediated recombination. (J:86465)
