Germline Transmission:  Earliest citation of germline transmission: J:19220
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA neomycin resistance gene was inserted into exon 5. RT-PCR analysis on testis RNA derived from hemizygous male mice demonstrated that no detectable transcript was produced from this allele, and western blot analysis on extracts of testes, liver, kidney and brain of hemizygous male mice confirmed that no stable encoded protein was made.
