FIG. 2.
Effect of 1 mg of bLf per ml on adenovirus antigen synthesis. Lactoferrin was incubated with the virus (1 h, 37 or 4°C) or with the cells (1 h, 37 or 4°C) before the viral adsorption step (1 h, 4°C). Virus antigen synthesis was monitored 24 h after infection by immunofluorescence. The data represent the mean of at least quadruplicate samples. For each sample, 600 cells were examined.
