Mutation description

Allele Type: Targeted (Null/knockout, Reporter) Mutations: Insertion, Intragenic deletion Mutation details: Exons 6 and 7 were replaced with an IRES-lacZ and inverted neo cassette via homologous recombination. RT-PCR and western blot analysis confirmed the absence of mRNA and protein expression in homozygous embryos and extraembryonic coelomic fluid, respectively. (J:156013)
