Figure 6

Mass distributions of the FGF-bound dp10 molecules at several different protein/heparinoid molar ratios. Mass distributions of the dp10 chains involved in formation of 1:1 complexes (red traces) are calculated based on the ionic signal of FGF·dp10+7 species, those for 2:1 (blue traces) and 3:1 (green trace) complexes are calculated based on the ionic signals of FGF2·dp10+12 and FGF3·dp10+14 species, respectively. The colored boxes indicate the mass ranges corresponding to the dp10 species with varying levels of sulfation.
