A model analytical chip was prepared by coupling 4 phage antibody clones from mouse and 1 clone from human to the surface of carboxyl-terminated silicon. The lymphocytes from healthy donors were selected as normal cells, while HeLa cells were selected as tumor cell. The whole proteins were labeled by fluorescent dye Cy3 after isolation from lymphocytes and HeLa cells, and then reacted with the analytical chip. A different binding pattern was obtained. Our results showed that the protein chip made of phage antibodies was able to recognize the proteome from different cells.
