A mixed self assembling monolayer (mSAM) chip with attached heparin was developed to analyze heparin-protein interactions using a Reichert Inc, SR7000, surface plasmon resonance (SPR) instrument. The heparin was attached via streptavidin-biotin linkage where the streptavidin was covalently coupled to the mSAM and biotinylated heparin bound to it. These chips were then used to quantify the interactions of fibroblast growth factor-2 (FGF-2) with the surface bound heparin. Kinetic rate constants of association and disassociation were calculated. The association data of FGF-2 with heparin was fit to a single compartment, well-mixed model as the data did not exhibit mass transfer limitations. The results suggested that rebinding was prevalent and observed disassociation rates differed significantly in the presence of competing soluble heparin during disassociation. Our results indicate that the Reichert instrument and mSAM chips can be used to analyze heparin-protein interactions but that a careful protocol, outlined in this thesis, should be followed to obtain optimal data.
