The rapid concentration and purification of influenza virus from allantoic fluid

Influenza virus was quantitatively recovered from infectious allantoic fluid by precipitation with 8 per cent (wt/vol) polyethylene glycol 6000 (PEG-6000). Virus concentrated by PEG-6000 treatment was rapidly purified by gel permeation chromatography through controlled pore glass beads. The purity of virus preparations achieved by this method, when judged… CONTINUE READING
