Inhibition of baculovirus infection with heparin. Baculovirus was incubated with the indicated concentrations of heparin for 1 hour prior to a 1-hour adsorption of the baculovirus-heparin mixture to HT1080 cells for infection. GFP expression was analyzed 48 hours post-infection using a flow cytometer. (a) Baculovirus was used at an multiplicity of infection (MOI) of 1. (b) Baculovirus was used at MOI of 2. Each point represents the average percentage decrease in GFP expression. The values represent the mean ± standard error of the mean (SEM) of triplicate experiments (*P ≤ 0.05, when compared to 0 µg/ml of heparin).
