Pall Corporation out of Port Washington, NY has released a new blood filtration system that can screen out leukocytes, as well as prions. The Leukotrap Affinity Plus System already obtained European approval and is meant to be used as a filter for donated blood, that might be contaminated by prions. Prions, of course, are responsible for spongiform encephalopathy, and are difficult to detect since carriers often are not aware of their condition until symptoms arrive.
