| Abstract: | An electrode for the determination of guanine was prepared, which employed brain tissue of rat as the biocatalyst and an ammonia gas sensing electrode as the base electrone.Its response characteristics, buffer conditions and strategies of immobilization were studied.The slope of guanine response curve E-lgGuanine] is 46.5 mV/decade, linear range is 2.0×10-5～6.3×10-4 mol/L, lifetime is over 28 days. |
