Preparation and characterization of FGF2-SPION. (A) Schematic representation of conjugation of FGF2 to SPION using carbodiimide chemistry. Immunoblot and iron staining (B) and quantification of FGF2 (C) and iron (D) showing successful conjugation and recovery. Labels 1-4 denote FGF2, FGF2-SPIONs, supernatant and SPIONs, respectively. Histograms of dynamic light scattering (E), zeta potential (F), and detailed physiochemical data (G) for SPION and FGF2-SPION. Data represents mean + SEM for at least 3 independent synthesis.
