Figure 2From: Simplified production and concentration of lentiviral vectors to achieve high transduction in primary human T cellsConcentration of a second generation packaging system generates virus with superior transduction efficiency in primary CD45RA+T cells. A. The total transducing units generated using second and third generation packaging systems. B. The level of transduction for the second and third generation packaging systems in CD45RA+ T cells as measured by flow cytometry. Data represents mean ± s.d. of three independent preparations. ***P < 0.001 using Students t-test.Back to article page
