The enzyme-linked immunospot assay was used to detect antibody-secreting cells from mice immunized against three human colon adenocarcinoma cell lines (Colo-205, SW 620, and SW 1116) on dishes coated with these cell lines. Antibody-secreting cells were detected by the development of a dark granular precipitate ('spot') using immunoenzymatic techniques where secreted antibody had bound to cell surface antigen. Spots can be detected by the naked eye and can be enumerated under low-power magnification. This method is specific, easily performed, versatile, and, together with conventional enzyme-linked immunosorbent assay techniques, allows for quantification of secreted antibody.

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.
