摘要: 建立酶联免疫方法以检测食品中恩拉霉素的残留,采用戊二醛法,偶联半抗原恩拉霉素(Er)和载体牛血清白蛋白(BSA)或卵清白蛋白(OVA),制备人工免疫抗原和人工包被抗原,分别为Er-BSA和Er-OVA。经紫外光谱鉴定,在紫外270~280 nm波长处得到Er-BSA和Er-OVA特征性偶联吸收峰。试验结果表明人工合成的2个人工抗原均偶联成功。人工免疫抗原和人工包被抗原的偶联比均达到26∶1,为进一步制备抗血清和酶联检测方法的建立奠定了基础。

Abstract: In order to establish an enzyme-linked immunosorbent assay (ELISA) for examing residual Enramycin (Er) in food. The antibody with high titer and specificity must be firstly prepared. So it was necessary for antibody production to conjugate the hapten (Er) with a carrier protein to synthesize immunogent(antigen). Enramycin was coupled with carrier protein bovine serum albumin (BSA) to obtain immunogent (Er-BSA) by glutaraldehyde (GA) method and with ovalnumin (OVA) to obtain coating antigen(Er-OVA) by GA respectively. The successful linkage of Er-BSA and Er-OVA were identified by UV spectrophotometry. The UV spectral characterization demonstrated that Er-BSA and Er-OVA were successfully synthesized at 270~280 nm. The coupling ratios between Er and BSA or OVA were determined to be 26∶1, respectively.

Key words: Enramycin, synthesis of antigen, glutaraldehyde method
