Figure 2From: Concentration and purification of enterovirus 71 using a weak anion-exchange monolithic columnStep gradient elution profile of EV-71 in CIM® DEAE 8f tube monolith column. Loosely bound proteins were eluted in the first peak using 20% NaCl. Pure viral particles were eluted in second peak using 35% NaCl. The last peak eluted using 100% NaCl completely removed all the tightly bound proteins from the column.Back to article page
