A, Binding of GAL-F2, other anti-FGF2 mAbs and negative control mAb mIgG to human FGF2 measured by ELISA; B, Competitive binding ELISA of anti-FGF2 mAbs against biotinylated GAL-F2; C, Binding ELISA of GAL-F2 to human FGF2 (hFGF2) and mouse FGF2 (mFGF2). In C, the curves for control mIgG binding superimpose and cannot be distinguished.
