摘要:

为建立罗丹明B(rhodamine B)的免疫分析方法,采用戊二醛法,将半抗原罗丹明123 与载体牛血清白蛋白(BSA)及卵清蛋白(OVA)偶联制备免疫抗原R123-BSA 和包被抗原R123-OVA。经动物免疫实验证实人工抗原合成,并制备抗罗丹明123 的多克隆抗体,此抗体同时能够检测食品中的罗丹明B,且最低检测限为0.001ng/mL。

Abstract:

For establishing an enzyme-linked immunosorbent assay (ELISA) method for rhodamine B determination, a complete antigen R123-BSA and a coating antigen R123-OVA were prepared by coupling rhodamine123 with the carrier proteins of bovine serum albumin (BSA) and ovalbumin (OVA) using glutaraldehyde method, respectively. The synthesis of rhodamine123 artificial antigens was confirmed by animal experiments. A novel anti-rhodamine123 polyclonal antibody was prepared, which was successfully applied to the determination of rhodamine B in food with a limit of detection of 0.001 ng/mL. The development of anti-rhodamine123 antibody will provide a valuable tool for the determination of rhodamine B in food seasoning products.

Key words: rhodamine 123, rhodamine B, glutaraldehyde method, artificial antigen, enzyme-linked immunosorbent assay (ELISA)
