Figure 2. Interaction between the small molecules and growth factors.

Figure 2

An overview of the SPR analysis showing the interaction between the sugar mimetics and growth factors/cytokines (A). Small molecules (1–9) were immobilized on the photoaffinity-linker-coated gold substrates. Interactions were detected between the small molecules (1–9) and the growth factors in solution by SPR imaging as described under “Experimental Procedures”. The maximum SPR signal strength observed between the small molecules (1–9) and VEGF (B), or FGF-2 (C) are presented.
