The objective of this work was to examine the effects of solution pH and ionic strength on virus retention by the Viresolve ® NFP membrane. Experiments were performed using the bacteriophage fX174 as a model virus, with the virus retention data complemented by the use of confocal microscopy to directly visualize the capture of fluorescently-labeled fX174 within the filter. Experiments were performed with Ultipor® DV20, Viresolve® Pro, and Viresolve® NFP membranes using bacteriophage φx174 as a model virus. The filters were challenged with two batches of fluorescently-labeled phage: one labeled with red dye (Cy5) and one with green dye (SYBR Gold) to visualize captured phage from before and after the pressure release.
