TWO NEW IMMUNOSENSORS AND A BIOSENSOR FOR BUFFALO MILK

摘要

The increasing commercial interest in exploiting the therapeutic value of Lactoferrin has stimulated the need for reliable assays for its determination in milk at the endogenous level. In this study we developed and characterized an immunosensor for the determination of antibacterial protein (Lactoferrin), with the aim of suggesting this procedure for routine control of an important foodstuff product such as buffalo milk. At the same time, using also another new electrochemical immunosensor for the measurement of immunoglobulin G, it proved possible to determine also immunoglobulin G in the same buffalo milk samples. Briefly, milk contains several protective proteins, including Lactoferrin and immunoglobulin G, that can contribute to the preservation of milk. In the present paper we successfully studied two new immunosensor devices for the analysis of both of these important proteins.
