  Hapten Synthesis and Antibody Development for Polychlorinated Dibenzo-p-dioxin Immunoassays

  摘要：

  This paper reports the synthesis of haptens and the generation and preliminary evaluation of polyclonal antibodies for the detection of dioxins such as TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) by ELISA (enzyme-linked immunosorbent assay). These novel haptens contain unsaturation between the halogenated dibenzo-p-dioxin ring system and the protein to which it is conjugated, presenting a rigid handle structure. The substitution pattern is identical with or similar to that of TCDD (i.e., 2,3,7,8- or 1,2,3,7,8-). Finally, the haptens lack polar groups for hydrogen bonding. In direct binding assays using the new polyclonal antibodies there was excellent recognition of hapten-protein conjugates, including recognition of those hapten conjugates that were not used as immunogens (i.e., assay systems heterologous in hapten structure). These haptens do elicit selective immune responses in rabbits. Their evaluation in an ELISA format demonstrated the usefulness of these haptens for the detection of dioxins. An IC50 of 0.8 ng/well (16 ng/mL) was observed for an unoptimized system that used 2,3,7-trichloro-8-methyldibenzo-p-dioxin as an analytical surrogate standard.

• Chromatography-Free Wittig Reactions Using a Bifunctional Polymeric Reagent
  作者：Peter Shu-Wai Leung、Yan Teng、Patrick H. Toy

  DOI：10.1021/ol1021614

  日期：2010.11.5

  The first example of a polystyrene bearing two distinct reagent groups has been prepared. This phosphine and amine functionalized material was used in one-pot Wittig reactions with an aldehyde and either an α-halo-ester, -ketone, or -amide. Due to the heterogeneous nature of the polymer, the desired alkene product of these reactions could be isolated in excellent yield in essentially pure form after

  已经制备了带有两个不同试剂基团的聚苯乙烯的第一个例子。该膦和胺官能化的材料用于与醛和α-卤代酯，-酮或-酰胺的一锅法Wittig反应中。由于聚合物的非均质性质，仅在过滤和除去溶剂后，就可以以优异的收率以基本纯净的形式分离出这些反应的所需烯烃产物。
