摘要:

为实现呋喃唑酮(furazolidone,FZD)的快速定量检测,本研究制备了抗FZD全抗原的单克隆抗体,建立了抗FZD的单克隆抗体酶联免疫检测方法。结果表明,FZD单克隆抗体在质量浓度为10~500 ng/mL范围具有较好的线性,IC50值为0.06 μg/mL,最低检测限为6.92 ng/mL,对于其他硝基呋喃类抗生素及其代谢物均不存在交叉反应。该方法重现性较好,平均误差为6.54%,回收率为76.84%~88.31%。

Abstract:

Based on the hapten of furazolidone (FZD), a monoclonal (mAb)-based enzyme-linked immunosorbent assay
(ELISA) method for the detection of FZD was established after the preparation of mAb against FZD-bovine serum albumin
(BSA). The linear range for furazolidone detection was 10–500 ng/mL, and the IC50 was 0.06 μg/mL with a lowest detection
limit of 6.92 ng/mL. Meanwhile, the mAb showed almost no cross reactivity with other nitrofurans or their metabolites. This
method had good reproducibility, with an average error of 6.54%. In tested samples, the recovery for furazolidone addition
was 76.84%–88.31%.

Key words: furazolidone (FZD), monoclonal antibody (mAb), enzyme-linked immunosorbent assay (ELISA)
