FIG. 2.

MBG and EBO-Z GP dictate similar ranges of infection in a panel of mammalian cell types. Infections with constant inocula of MBG (A) and EBO-Z (B) luciferase pseudotypes were performed for 48 h in parallel with infections by Ampho pseudotype virus to estimate cell type variability in luciferase reporter expression after virus entry. Data are the means derived from three separate infections (± standard error of the mean). +, cell line permissive to infection by pseudotype virions carrying the puromycin resistance gene driven by a simian virus 40 promoter but nonpermissive as assessed through infection by pseudovirions carrying the luciferase reporter gene driven by the HIV-1 long terminal repeat promoter.
