Targeted Allele Detail
Symbol: Ifnb1tm2.1Lien
Name: interferon beta 1, fibroblast; targeted mutation 2.1, Stefan Lienenklaus
MGI ID: MGI:4355683
Synonyms: IFN-Bflox beta-luc, IFN-Bfloxbeta-luc
Gene: Ifnb1  Location: Chr4:88522025-88522774 bp, - strand  Genetic Position: Chr4, 41.91 cM
Germline Transmission:  Earliest citation of germline transmission: J:151854
Parent Cell Line:  Bruce 4 (ES Cell)
Strain of Origin:  B6.Cg-Thy1a
Allele Type:    Targeted (Conditional ready, No functional change)
Mutation:    Insertion
Mutation detailsA loxP site was inserted 42 bp upstream of the lone coding exon and a Frt-flanked neomycin cassette, another loxP site, and a myc-tagged luciferase coding sequence were inserted downstream of the exon in the BstAPI restriction site. After targeting in C57BL/6 ES cells, the neomycin cassette was removed by crossing founder mice with FLP-deleter mice. A poly-A sequence upstream of the luciferase cassette prevents transcription of the reporter until the endogenous exon is floxed. (J:151854)
