中文摘要:

以杀菌剂百菌清为基础制备人工抗原，分别使用Native-PAGE电泳法、SDS-PAGE电泳法和紫外分光光度法对其进行鉴定，并测定各人工抗原的偶联比。研究结果表明，使用紫外分光光度法鉴定人工抗原时，存在假阳性情况，此时仍可计算出人工抗原的偶联比。若使用假阳性人工抗原进行免疫，所获得的抗体效价较低，对载体蛋白的识别能力较强，不适合用于免疫检测技术的建立。

英文摘要:

Research purpose of the paper was comparing the commonly identification methods of Artificial antigen, such as Native-PAGE electrophoresis, SDS-PAGE electrophoresis and UV spectro-photometry. In the paper, as the fungicide chlorothalonil was the based compound to preparate the artificial antigens. Native-PAGE electrophoresis, SDS-PAGE electrophoresis and UV spectro-photometry were used of qualitative analysising the artificial antigens, respectively. The results showed that the UV spectrophotometry identification method might cause the false positive, but it still could calculate the coupling ratio of the artificial antigen. If the false positive artificial antigen was used as immunizing antigen, the titer of antibody be low, while, the recognition ability with the carrier protein be strength, which is not suitable for establishing the immunoassay technology.
