Inhibition of HIV infection by rhizosecreted CV-N following IEX. Luciferase assays were performed by incubating the reporter cell line TZM-bl with HIV_BaL and rhizosecreted IEX-purified CV-N or E. coli derived CV-N (initial concentration of 1.75μg/ml and 10 μg/ml, respectively) or PBS. The viral infectivity is plotted against the dilution of the sample, and results are the mean and SEM of three experiments. The table indicates the IC₅₀ of rhizosecreted IEX-purified and E.coli-derived CV-N. Calculations were performed using GraphPad Prism software.
