This procedure allows fast genotyping of a large number of mice with long-distance PCR using TaqPlus Long DNA polymerase. Usually, the results are ready the day after mice ear clipping. Additionally, by amplifying several specific overlapping fragments and analyzing these fragments, a more detailed characterization of the region of interest can be realized. This procedure will have wide application in transgenic mice technology and may be useful for detailed analysis of chromosomal loci with extensive modifications, either introduced by homologous recombination or naturally occurring (i.e., deletions and insertions).
