It is desired that many antigenic indicators for health care should be examined at the same time from the viewpoint of diagnosis and biosensor development. The surface plasmon resonance technique is a preferable method for time saving and real time detection of antigen as reported so far. In this study, simultaneous detection for human hemoglobin (for colon cancer) and human serum albumin (for kidney disease) was conducted using their specific monoclonal antibody on SPR apparatus equipping two detecting cells. The signals corresponding to the various concentrations of above two antigens were simultaneously obtained.
