Pulsed-field gel electrophoresis is a technique used for the separation of large deoxyribonucleic acid (DNA) molecules by applying to a gel matrix an electric field that periodically changes direction. TEP has a CHEF Mapper XA system from Bio-rad, which has a superior resolution in the range of 100 bp to 10 Mb. TEP provides services including running PFGE gel, making plugs, etc.
