A Simple Separation Method of the Protein and Polystyrene Bead-Labeled Protein for Enhancing the Performance of Fluorescent Sensor

Figure 1

Schematic illustration of a simple separation method of the protein and protein conjugated with polystyrene (PS) beads. (a) Intensity of fluorescence by a specific binding of the protein conjugated with PS beads decreased due to a specific binding of the nonconjugated protein, expressed as residue protein. (b) Residue protein and protein conjugated with PS beads were separated by the dielectrophoresis (DEP) force in different microholes, respectively.
