N2 - A surface plasmon resonance (SPR) array imaging method is outlined for label-free cell profiling. Red blood cells (RBCs) were injected into a flow chamber on top of a spotted sensor surface. Spots contained antibodies to various RBC membrane antigens. A typical sensorgram showed an initial response corresponding to cell sedimentation (S) followed by a specific upward response (T) corresponding to specific binding of cells during a critical wash step. The full analysis cycle for RBC profiling was less than 6 min. The sensor surface could be regenerated at least 100 times, allowing the determination of a cell surface antigen profile of RBCs.
