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