摘要: 实验采用碳二亚胺法将卡巴氧代谢物喹喔啉-2-羧酸(QCA)与牛血清白蛋白(BSA)偶联,采用用混合酸酐法将其与卵清白蛋白(OVA)偶联,分别将其作为免疫原(QCA-BSA)和包被原(QCA-OVA)进行抗血清的制备及ELISA实验。经过多次动物免疫及EILSA实验,结果表明,获得了高效价的特异性抗体。

Abstract: The QCA is coupled to BSA as an immunogen by the method of EDC,as well,the coating antigen(QCA-OVA) were produced by the method of MA.The immunogen and coating antigen have been identified by the method of ultraviolet full wavelength scanner.Polyclonal antibodies against QCA have been raised in four rabbits and purified by using a saturated ammonium sulfate method.The sensitivity and cross-reactivity of polyclonal antibody have been demonstrated in ELISA test.The results showed that the QCA antiserum have a very high degree of sensitivity and specificity.
