Abstract
Provided is a method for detecting an antigen without use of a labeled-antibody. A support having an antibody and a multi-copper oxidase CueO immobilized thereon is brought into contact with a first buffer solution containing the antigen, a current is measured by a potentiostat method using the support and a second buffer solution, and when the measured current is greater than or equal to 1.5×(blank value), it is determined that the antigen exists. The second buffer solution contains a substrate of the CueO and has an ionic strength falling within a range of not less than 0.3 mM and not more than 1.0 mM.
