Figure 2. Efficient concentration with minimal loss. Lentiviral supernatant from a pLVX-ZsGreen1 vector was concentrated from 3 ml down to 30¥ìl using the Lenti-X Concentrator Reagent and reflects a 100-fold increase in viral titer. The total amount of virus contained in each sample is also indicated, which shows that the resuspended pellet captured 90% of the virus present in original sample. Samples were titrated on HT1080 cells and analyzed by flow cytometry 48 hr post-transduction.
