PURPOSE:To measure the concn. of a liquid to be tested as potential difference, by applying crosslinking treatment to the protein A-albumin mixture membrane applied to a metal wire using a dialdehyde compound. CONSTITUTION:The protein A-albumin mixture membrane applied to a metal wire is subjected to crosslinking treatment using a dialdehyde compound. As the metal wire, for example, one composed of silver/silver chloride and having a size capable of forming an electrode is used. Subsequently, the crosslinking treatment using the dialdehyde compound is performed in order to immobilize the protein A-albumin mixture membrane applied to the metal wire. Then, the part not provided with the treated film is coated to form an immune sensor electrode which is, in turn, connected to an electrometer using a silver/silver chloride electrode as a reference electrode. By this method, the concn. of a liquid to be tested can be measured as potential difference. |
