A label free immunosensor for detection of Fc receptors expressed on cell surface was developed and characterized by Quartz Crystal Microbalance (QCM) transducer. Taking advantage of the characteristics of single chain fragment variable (scFv) recombinant antibody and the multivalency of an antibody, the engineered recombinant scFv was immobilized onto pre-formed functionalized self-assembled monolayers (SAMs) template surface. The monomeric ScFv can bind with the CH1 region of any rabbit IgG to form a highly oriented IgG layer with its Fc portion pointing toward solution phase. This results in a highly oriented Fc sensor that can be used to study the thermodynamics and kinetics of binding between Fc portion of immunoglobulin and cell surface Fc receptor (FcR), an important area of the immune system. The Fc sensor was used to study the binding between Staphylococcus aureus (S. aureus) and Macrophage with Fc receptor. Parallel characterization of cell surface Fc receptors in the same samples by ELISA was also performed.
