摘要： The present invention has an object of providing a method by which two kinds or more of molecules can be separated each other by using dielectrophoretic forces. The present invention comprises two methods. The first method is a method comprising forming a complex substance of a “specific molecule” containing in a sample, and a “substance capable of changing dielectrophoretic properties of the specific molecule”, which binds to the “specific molecule” contained therein, and thereby separating the complex substance and the molecules other than the specific molecule in the sample from each other. The second method is a method comprising placing a solution in which two kinds or more of molecules are dissolved under a strong electric field strength, that is, under a nonuniform electric field having an electric field strength of 500 KV/m or higher, by using dielectrophoretic forces.

摘要： To suppress temperature variations of sample fluids within flow channels for electrophoresis, in a method for controlling temperatures within micro flow channels. When controlling the temperatures of sample fluids within micro flow channels of electrophoresis chips, in which flow channels through which electrophoresis occurs by application of electrical potential differences can be switched, temperature variations of the sample fluids within the micro flow channels, caused by differences in heat generated by the sample fluids prior to and following the switching of the flow channels, are predicted. Control properties for temperature control in order to cancel the temperature variations are changed during the switching of the flow channels.

摘要： Internal standard concentration is normalized as an independent parameter through measuring a buffer conductance in a system with characterized reagents and in a defined assay device. The conductivity of a fresh internal standard solution is measured whether in isolation or as part of a system that is subject to a uniform variation such as evaporation or condensation. Collected conductance measurements may be used to normalize assay signals that are dependent upon fluidic channel dimensions, such as fluorescence assay signal measurement.
