Mutation:    Insertion
Mutation detailsIn one homologous recombination event an IRES Beta-geo cassette was inserted into the 3' untranslated region and in a second homologous recombination event a mutation changing codon 12 in exon 1 into a valine was inserted along with a floxed transcriptional stop and PGK-Hydro cassette. This resulted in bicistronic Cre recombination-dependent expression of the oncogenic Kras allele and Beta-geo. (J:86101)
