Nucleic acid introduction method, nucleic acid detection method, biomolecule analysis method, array device for biomolecule quantification, and biomolecule analysis kit

An array kit device, comprising:

• a base having a plurality of wells configured to be filled with an aqueous solution;
• a cover positioned over the base and including a plurality of waste liquid vessels such that the cover covers openings of the wells and forms a gap forming a channel between the cover and the opening of the wells;
• and
• a spacer member connecting the base and the cover such that the spacer member sections the gap into a plurality of watertight portions corresponding to the plurality of waste liquid vessels in the cover, respectively,
• wherein the cover has a plurality of injection ports positioned to inject an oleaginous sealant into the plurality of watertight portions, respectively, and a plurality of discharge ports positioned apart from the plurality of injection ports respectively such that the plurality of discharge ports discharges surplus amounts of the aqueous solution in the plurality of watertight portions outside the wells by the oleaginous sealant injected into the plurality of watertight portions from the plurality of injection ports, each of the waste liquid vessels is formed on an opposite side of the gap and configured to collect the surplus amounts of the aqueous solution discharged from the plurality of watertight portions via the plurality of discharge ports respectively such that the plurality of waste liquid vessels is directly communicating with the plurality of discharge ports, respectively, and the cover is formed such that each of the discharge ports has an opening end formed on a respective waste liquid vessel side and is made of a material that is selectively non-transmissive to light in a specific wavelength range.
