title: Determination of bacteriophage genome size by pulsed-field gel electrophoresis.
abstract: Standard agarose gel electrophoresis is extensively used to resolve DNA fragments from 0.2 to 40-50 kb. Larger fragments of genomic DNA or whole viral genomes can only effectively be resolved by pulsed-field gel electrophoresis (PFGE), which extends the range of molecular separation from 200 bp to 12 Mb.
