Abstract:
We constructed an integrated immunosensor system to combine a quartz crystal microbalance with the agglutination reaction of immunized latex beads. C-reactive protein (CRP) induced an immunoreaction due to the latex bends with anti-CRP antibody. We succeeded in determining the concentration of CRP necessary in human serum for disease diagnosis using a CRP Sensor I.
