Fig. 6. The FGF10-FGFR2b complex shows greater binding to purified intact HUAEC
perlecan than FGF10 or FGFR2b alone, and binding of the complex is reduced by
heparanase treatment. (A) SPR analysis of FGF10, FGFR2b, and
FGF10-FGFR2b complex binding to intact perlecan. Proteins were diluted in
HBS-P containing 0.1 µg/ml heparin. (B) SPR analysis of FGF10-FGFR2b
binding to perlecan before and after heparanase treatment. Heparanase (5
µg/ml at 5 µl/minute) was applied to the chip surface. RU, response
units.
