Studies from E.J. White et al in the area of clinical chemistry described

"Epidemiologic studies require identification or typing of microbial strains. Macrorestriction DNA mapping analyzed by pulsed-field gel electrophoresis (PFGE) is considered the current gold standard of genomic typing," scientists in the United States report.
"This technique, however, is difficult to implement because it is labor-intensive and difficult to automate, it requires a long time to obtain results, and results often vary between laboratories. We used direct linear analysis (DLA), which uses a single reagent set and long fragments of microbial genomic DNA to identify various microbes. In this technique, an automated system extracts fragments exceeding 100 kb from...
