<p>A method of carrying out a biochemical assay, comprising carrying out a specific binding reaction to localise an amount of a substance either directly or indirectly capable of causing or affecting the generation of a component of a redox couple, able to take part in a redox reaction at an electrode, and measuring electro-chemically the amount of the said component which takes part in the said reaction at the electrode. The electrode surface is formed of a hydrophilic non-porous resin-bonded graphite material substantially free of platinum-group metals. The reaction which takes place at the electrode is the interconversion of ferricyanide ion and ferrocyanide ion.</p> |
