BIOMOLECULAR ANALYSIS DEVICE

摘要

The present invention provides a biomolecular analysis device which suitably realizes sample adsorption. According to an embodiment of the present invention, a biomolecular analysis device (1) includes: a sample separating section (5); a pressing tool (6); and a transfer film (7) which is provided between the sample separating section (5) and the pressing tool (6). The pressing tool (6) (i) presses, with a fixed pressure, the transfer film (7) toward a second opening (58) of the sample separating section (5) and (ii) restricts a region which is located between the sample separating section (5) and the second buffer solution tank (4) and in which there is a buffer solution.

主权项

1: A biomolecular analysis device in which (i) an electric current is allowed to flow through a separation medium via a buffer solution so that a biomolecule sample in the separation medium is separated into separated biomolecule samples and then (ii) the separated biomolecule samples are released from the separation medium and then adsorbed to an adsorbing member, said biomolecular analysis device comprising:
a first electrode; a second electrode; a separating section for storing the separation medium, the separating section having (i) a first opening which is made on a side facing toward the first electrode and (ii) a second opening which is made on a side facing toward the second electrode; and a pressing tool which is located between the separating section and the second electrode, the pressing tool sandwiching an elastic member, which has an insulating property, between a first structure and a second structure, the first structure being provided on a side facing toward the separating section, and the second structure being provided and positionally fixed on a side facing toward the second electrode, the first structure having a first through-hole which is located at a position facing the second opening and which penetrates through the first structure from the side facing toward the separating section to a side facing toward the second electrode, the second structure having a second through-hole which is located at a position facing the second opening and which penetrates through the second structure from a side facing toward the separating section to the side facing toward the second electrode, the adsorbing member being provided between the second opening and the first through-hole, the elastic member pressing the first structure toward the separating section, the elastic member having a loop shape which surrounds an opening of the first through-hole on the side facing toward the second electrode and which surrounds an opening of the second through-hole on the side facing toward the separating section such that the elastic member having the loop shape restricts a channel of a buffer solution between the opening of the first through-hole and the opening of the second through-hole.
