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.

Automated two-dimensional electrophoresis apparatus and instrument constituting the apparatus

There is provided an electrophoresis device including an insulator that includes: a first-separating-medium storing section for storing therein a first separating medium; a first opening and a second opening that are in communication with the first-separating-medium storing section and for defining a direction of separation on the first separating medium; and a third opening that is covered with a penetrable insulating thin film, wherein the first separating medium storing section is in communication with outside via the first opening and the second opening. There is also provided an electrophoresis apparatus including the electrophoresis device. This realizes an electrophoresis apparatus, and a device therefor, that enables an operator to sample separated proteins without ever making contact with the electrophoresed gel, and that can easily be used with various types of analyses, thereby improving convenience of electrophoresis.
