摘要:
A method of separating a protein by gel electrophoresis, which comprises a staining step for bringing a protein-containing sample into contact with a staining liquid containing a staining agent, a surfactant and a buffer solution, and an electrophoresis step for subjecting the protein-containing sample after the staining step to gel electrophoresis.According to the present invention, using a staining liquid containing a surfactant such as SDS and the like, a protein-containing sample can be stained in a short time, and can develop color with high sensitivity. In addition, since an excess staining agent migrates earlier than protein by electrophoresis, a washing operation is not necessary. Furthermore, by staining, after the first dimension electrophoresis, with a staining liquid containing a surfactant such as SDS and the like, the second dimension electrophoresis can be performed immediately. As a result, the number of steps can be reduced as compared to conventional protein separation methods, and the separation operation can be simplified. Hence, a method capable of staining and separating a protein conveniently and quickly by electrophoresis can be provided.

The present invention is to provide a sample separation instrument used in a sample separation apparatus which includes: holding means for holding a first medium supporter which supports a first medium; and driving means for moving fixing means or the holding means in a direction parallel or perpendicular to a plane whose sides extend in the first direction and in the second directions. The sample separation instrument includes an insulator for storing a second medium which allows a sample separated in the first medium in the first direction to be further separated in the second direction different from the first direction, wherein: the insulator includes a first opening and a second opening each of which defines the second direction in which the second medium is electrified, and the second opening has a shape which allows the first medium containing the separated sample to be attached to the second medium along the first direction. The present invention realizes automation of the two-dimensional electrophoresis to enhance the convenience of the two-dimensional electrophoresis, to less depend on the operator's skill, and to enhance the reproducibility of the electrophoresis result.

A device for electrophoresis applies a voltage to a medium in contact with a plurality of electric conductors so that a potential of adjacent conductors is within a certain range. This allows preventing decline in electrophoresis speed. A device for electrophoresis and transfer includes an electrode having a plurality of electrode regions being insulated one another and arranged in a specific direction. This allows providing a practical and easy-to-use device for electrophoresis and transfer. A device for transfer alters an applied voltage or applied voltage duration to a certain position to another position. This allows improving transfer efficiency.

With the use of a chip (4) for electrophoresis and transfer including a transfer membrane (1) and an electrophoretic gel that is integrated with the transfer membrane (1), separation of a sample by electrophoresis and transfer of the sample separated to the transfer membrane (1) are carried out consecutively. This allows molecules separated on the gel by electrophoresis to be accurately transferred to the transfer membrane.
