I am looking for a way to extract DNA from single celled organisms which
may be contaminating animal feed samples. Since the density of these
organisms is similar to the feed particles themselves (when ground up and
solubilized in water) simple centrifugation is not an option. Filtration
has not been successful either because the feed clogs the filters.
Does anyone out there have experience with or a reference for total
DNA extraction/harvest from extremely dilute aqueous samples?
Thanks in advance for you responses.
