内容記述 |
Voltammetric sensing of phosvitin was carried out based on an interaction between ruthenium(III) and phosvitin. The electrode response of hexaammineruthenium(III) was measured using a glassy carbon electrode. When phosvitin was added to 0.1 M phosphate buffer (pH 7.0) containing hexaammineruthenium(III), a new peak was observed due to the formation of ruthenium (III)-phosvitin complex. On the other hand, it was expected that iron strongly combines with phosphate groups of phosvitin. Although a new peak did not appear in the incubation of hexacyanoferrate(III) and phosvitin, the peak current of hexacyanoferrate(III) decreased as the concentration of phosvitin increased. The electrode responses of hexaammineruthenium(III) and hexacyanoferrate(III) were linear and ranged from 2.5 x 10-10-5.0 x 10-9M and 5.0 x10-8-5.0 x 10-7M, respectively. As a result, the interaction between hexaammineruthenium(III) and phosvitin was stronger than that between hexacyanoferrate(III) and phosvitin. The decrease of the peak current with phosphoprotein such as ovalbumin and casein was observed. The change of the electrode response with phosvitin was the greatest in those proteins. Consequently, the sensing system had a high selectivity for phosvitin. |
