FIG. 2.

Digestion of GAGs decreases the ability of cells to bind SV. CHO monolayers were predigested with various concentrations of heparinase I or chondroitinase ABC, and the amount of radiolabeled virus bound after 1 h at 4°C was measured. Each point is the mean of three measurements. ∗, P of <0.05 versus no enzyme.
