Figure 2.

Examples of binding by human H3N2 isolates that diverge from the pattern shown in Figure 1. The boxes represent each virus from 1968 (left) to 2010 (right). Binding is color coded as percent of the highest signal, from 100% (red) through 50% (green) to 10% (violet) with white representing <10%. These are the highest-binding glycans for the strains in years indicated. Data from Gulati et al. [14].
