自 Yalow 和 Berson 1956年建立放射免疫测定法以来,目前已广泛应用于生物学和医学方面。在家畜传染病诊断和鱼类的促性腺激素研究中应用放射免疫测定技术也有过报道,但在植物病害研究中应用此法,尚处于探索阶段。本文报道了我们1979年对白叶枯病菌标记、抗体血清制备和固相放射免疫测定等方面进行的白叶枯病菌测定方法,及其对接菌稻种、植株中病菌含量测定的初步试验总结。 Since the establishment of radioimmunoassay in 1956 by Yalow and Berson, it has been widely used in biology and medicine. Radioimmunoassay has also been reported in the diagnosis of livestock diseases and the study of gonadotrophins in fish. However, the application of this method in plant disease research is still under exploration. In this paper, we report the preliminary test results of the methods for the determination of Bacterial leaf blight, the preparation of antibody sera and the solid phase radioimmunoassay in 1979, and the preliminary test on the determination of the pathogenic bacteria in the inoculated rice and plants.
