 This study compared the effectiveness of five different filter types when used to collect DNA from seawater samples. The researchers found that the Dinesi and Mobio Power Water DNA isolation kits produced similar results, while phenol slash chloroform extractions yielded different results. They recommended using either Dinesi or Mobio with PS, PCTE, PVDF, or NC filters for cross-trophic level comparisons. This article was authored by Annie Jurius, Jesse Port, Colin J.
