摘要:

用碳二亚胺(EDC)法将14位羟基修饰的雷公藤内酯醇(TP)和不同的蛋白栽体(阳离子化牛血清白蛋白、鸡卵清蛋白)偶联合成TP的人工免疫抗原和检测抗原,紫外光谱鉴定偶联效果,计算偶联率.利用免疫抗原免疫小鼠,制备小鼠多克隆抗体,用检测抗原分析血清抗体效价,利用抗原竞争EUSA分析抗体特异性,为进一步研究TP的分子作用机理以及制备TP的单克隆抗体奠定基础.

The triptolide 14′-succinate was synthesized from the succinyl anhydride and triptolide,then the derivative was conjugated to the cBSA protein carrier to produce a suitable immunogen,using the EDC method.OVA was used to synthesize the analytical immunogen.The conjugation was proven to be successfully validated by UV spectral analysis.BALB/c mice were immunized by this conjugate and the polyclonal antibody against triptolide was prepared.The titer of the polyclonal antibody was measured and the specificity of the polyclonal antibody was verified.The preparation of polyclonal antibody against triptolide provides a useful tool for further preparation of monoclonal antibody against triptolide and elucidation of molecular mechanism of triptolide function.
