Figure 4. Inhibition of MAV-1 attachment to A549 cells by chemically modified heparins.

A competition assay with two different concentrations of (un)modified heparin was performed essentially as described in Figure 1. Means (±SEM) of four independent experiments are shown (each condition performed in duplicate). *, P<0.05 and **, P<0.01 versus the inhibition seen with unmodified heparin.
