Fig. 6From: Effects of physical and chemical factors on pseudorabies virus activity in vitroStorage time vs. virus titer curves. a: PRV (B). b: PRV (K). PRV solution was aliquoted into 1.5 mL EP tubes at 200 µL per tube and then stored at 26℃, 4℃, -20℃, or -80℃. Samples were removed according to the experimental time points for virus titer determination, and the titer curves were drawn. The experiment was repeated three timesBack to article page
