The newcastle disease antigen ( nd . ag ) was immobilized in a graphite paste matrix Ab ，一种家禽传染病) 。把新城疫疾病抗体固定在碳糊电极中。
2.
The determination is accomplished by amperometry using tetramethylbenzidine and h2o2 as the substrates . two different graphite pastes were compared using either sol - gel or solid paraffin as binders . the sol - gel biocomposite showed a better response characteristics and higher reproducibility 我们比较了用溶胶-凝胶和固体石蜡为基质的免疫电极的不同特性，其中溶胶-凝胶免疫电极表现出更好的响应特性和更高的重现性，能检测到的nd
