DNA DETECTION METHOD AND REPORTER PROBE

摘要

An electrode where a capture probe (28a) is connected to the surface of a carbon electrode (21), a reporter probe (28c) labeled with an L-proline dehydrogenation enzyme (26), and an L-proline (25) serving as a substrate reactive with the L-proline dehydrogenation enzyme (26) are used. A target DNA (28b) is connected to the capture probe (28a) and the reporter probe (28c). By measuring the current value of the limiting oxidation current flowing through the carbon electrode (21) because of the reaction between the L-proline dehydrogenation enzyme (26) with which the reporter probe (28c) is labeled and the L-proline (25), the target DNA (28b) is detected.
