Fractionation technology from Digilab Biovision GmbH, Hanover, Germany, was adopted for the isolation of low molecular weight peptides (typically <15,000 Da) from human plasma ultrafiltrate. The 4 ultrafiltrates were analyzed for somatic phages, F-specific phages, and enteroviruses, and each sample was found positive for these viruses. The SalivaSac(R) was designed to improve the diagnostic use of saliva by collecting and processing an ultrafiltrate of saliva, facilitating analytical testing in a point-of-care or home environment. |
