Figure 6From: Targeting lentiviral vector to specific cell types through surface displayed single chain antibody and fusogenic moleculepH-dependent study of the fusion activity of various FMs. R18-labeled lentiviral vectors (FUGW/SC2H7-A2/FM) were mixed with liposomes (200 μM) for 1 minute. Virus-liposome fusion was triggered by adding the appropriate volume of acetic acid and measured by dequenching of fluorescent R18 using a spectrofluorometer.Back to article page
