Use of porcine interspersed repeat sequences in PCR-mediated genotyping
Abstract
PCR primers derived from porcine short and long interspersed repeat sequences were used to amplify DNA samples isolated from individual members of three-generation pig reference pedigrees. Subsequent high-resolution gel electrophoresis of both SINE and LINE-PCR products allowed direct visualisation of polymorphisms that segregated in a Mendelian manner. Additional polymorphisms were detected by Southern blotting of the gels described above followed by hybridization with simple sequence DNA. Genotyping by interspersed repeat-PCR exploits the natural architecture of the pig genome and allows the typing of polymorphisms by utilizing pre-existing sequence information.
