The Ames dwarf mouse phenotype is based on a homozygous single gene mutation in the Prop-1 gene that markedly extends life span. Since its discovery, interest in breeding these mice as a model to study retardation of aging has increased dramatically. However, the homozygous Prop-1 mutants are infertile, which necessitates breeding heterozygotes. Heterozygotes cannot be distinguished from the wildtype, while the homozygote dwarf phenotype only becomes apparent after about 3 weeks. Hence, there is a need for a simple test to genotype individual animals at an early stage for the absence or presence of one or two copies of the Prop-1 mutant gene. Here we present a Prop-1 genotyping protocol, based on a PCR reaction followed by a PflMI digestion.
