摘要:

以9-芴乙酸(fluorene-9-aceticacid,FLU)为原料,经活性酯法合成完全抗原FLU-牛血清白蛋白(bovineserum albumin,BSA)和FLU-卵清白蛋白(ovalbumin,OVA),偶联产物通过非变性聚丙烯酰胺凝胶电泳及紫外扫描法鉴定。使用FLU-BSA足垫免疫BALB/c小鼠获得多克隆抗体,间接酶联免疫吸附实验(enzyme linkedimmunosorbent assay,ELISA)测得多克隆抗体效价为51 200,间接竞争ELISA方法测得芴多克隆抗体的特异性,与荧蒽的交叉反应率为12%,与其他14 种多环芳烃交叉反应不明显。

Abstract:

Fluorene-9-acetic acid (FLU) was chosen as the hapten and was coupled with bovine serum albumin (BSA)
and ovalbumin (OVA) respectively to prepare complete antigens by active ester method. The complete antigens were
characterized by native polyacrylamide gel electrophoresis and ultraviolet spectrum. FLU-BSA was used to obtain
polyclonal antibody through footpad injection of BALB/c mice. The titer was 51 200 as measured by indirect enzyme linked
immunosorbent assay (ELISA), and the cross-reactivity with fluoranthene was measured by indirect competitive ELISA
to be 12% while having no obvious cross-reaction with 14 other kinds of polycyclic aromatic hydrocarbons (PAHs). This
ELISA method for fluorene can lay the foundation for further experimental research.

Key words: fluorene-9-acetic acid, complete antigen, polyclonal antibody, enzyme linked immunosorbent assay (ELISA)
