Claim 0:
1. A system comprising:
a microchip;
a table on which the microchip is loaded;
a controller; and
a lysis reaction unit,
wherein the microchip comprises:
a cell accepting section accepting cells obtained from a subject;
a lysis solution chamber storing a lysis solution for lysis of the cells;
a lysis reaction chamber in which lysis reaction of the cells is executed;
a first flow path communicating the cell accepting section directly to the lysis solution chamber; and
a second flow path communicating a bottom opening of the cell accepting section directly to the lysis reaction chamber,
wherein the lysis solution chamber, the lysis reaction chamber, the first flow path and the second flow path are configured as inadhesive sections between adhesively laminated elastic films;
wherein the first flow path is configured to allow the lysis solution stored in the lysis solution chamber to flow into the cell accepting section,
wherein the second flow path is configured to allow the lysis solution stored in the cell accepting section to flow into the lysis reaction chamber together with the cells and also allow the lysis solution stored in the lysis reaction chamber to flow back into the lysis reaction chamber,
wherein the lysis reaction chamber is configured to expand when the lysis solution is transferred from the cell accepting section into the lysis reaction chamber together with the cells and to have a capacity that is smaller than a capacity of the cell accepting section such that the lysis solution transferred into the lysis reaction chamber is restricted up to a capacity of the lysis reaction chamber,
wherein the controller is configured to control transferring of the lysis solution from the lysis solution chamber to the cell accepting section, transferring of the lysis solution containing cells from the cell accepting section to the lysis reaction chamber, and transferring of the lysis solution forward and back between the lysis solution chamber and the cell accepting section at a plurality of times,
wherein the lysis reaction unit is configured to heat lysis solution containing the cells in the lysis reaction chamber so as to execute the lysis reaction.
