FIG. 2.
VSV attachment is similar among different cell types. VSV particles were labeled with [35S]methionine. HeLa, LNCaP, and PC3 cells were incubated with equal amounts of radiolabeled VSV for 30, 60, and 90 min at 4°C. Radioactivity associated with each cell type was detected using a scintillation counter; data are expressed for each cell type as the cpm per cell as a percentage of the total input cpm over time.
