FIG. 4.

Binding of alphaviruses to immobilized GAGs. Ninety-six-well plates were coated with various GAGs, and the amount of radiolabeled virus that bound was assessed. (A) Binding of SV. (B) Binding of RRV. Ten thousand counts per minute of virus per well were used. Each bar represents the mean of four measurements. ∗, P of <0.05 versus uncoated wells. See the legend to Fig. 1 for abbreviations.
