The antibody is bound to an inert polymer support ,then exposed to reacts with the antigen at a different epitope is added. The second antibody used is one that has an enzyme attached to it that coverts a colorless or nonfluorescent substrate into a colored or fluorescent product. The amount of second antibody bound, and hence the amount of protein antigen present in the original sample, is determined by quantification of the intensity of color or fluorescence produced.

第二章：微波辐射下Pd配合物催化NaBPh_4与羧酸酐的偶联反应研究本章中我们在微波辐射条件下，研究了PdCl_2(PPh_3)_2催化NaBPh_4与羧酸酐偶联反应，合成出了十种不对称芳酮，并分别考察了微波辐射功率、辐射时间、溶剂和原料配比等因素对反应的影响，优选出了较佳的反应条件，并根据文献及实验结果，讨论了可能的反应机理。

The Suzuki reaction, the coupling of organoborate compounds with organic electrophiles catalyzed by Palladium complexes, is a valuable Csp2-Csp bond forming reaction. The reaction has been drawing increased attention in that the reaction permit the use of organoboron compounds that are thermally stable and inert to water and oxygen.In this section microwave promoted Suzuki reaction of phenylboronic acid with benzyl halides catalyzed by Pd(PPh3)2Cl2 DMF/H2O(v/v=10 : 2) was first reported.

第四章：微波辐射下Pd配合物催化端烯与芳卤偶联反应研究本章中我们在微波辐射条件下，研究了PdclZ(P Ph3)：催化端烯与芳卤的偶联反应，合成出了七种乙烯基化合物；并分别考察了微波辐射功率、辐射时间、原料配比、和PTc等因素对反应的影响，优选出了较佳的反应条件，并根据文献及实验结果，讨论了可能的反应机理。

Nevertheless, the yield of pinacol was also strongly affected by the steric environment surrounding the carbonyl group. The pinacol coupling of aromatic aldehydes has been achieved with high yields under such a condition. However, the diastereose-lectivities of pinacols were not satisfying. Unfortunately, the ketones and most aliphatic aldehydes appeared inert under the same reaction conditions.

然而， 呐偶合反应的产率受到羰基周围环境的立体位阻影响较大，在此条件下，锌粉能有效地促进芳香族醛类化合物进行水相呐偶合反应，得到的呐醇产率高，但非对映异构体选择性差，而脂肪族醛类化合物得到的呐醇产率较低，在同样的条件下，酮类化合物不能顺利进行呐偶合反应。
