We compare stabilizing effects of artificial and natural stabilizers for maintenance of binding activity of immobilized antibody on the gold surface of quartz crystal microbalance (QCM). Binding activity between immobilizing antibody and specific antigen was measured and considered as a calculated frequency shift with QCM-immunosensor after temperature increasing and long-term storage. According to the experimental results, one stabilizer among eight samples shows the best stabilizing effect for QCM-immunosensor.
