Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).
DMAE·NHS的合成是本论文的关键和难点,我们对文献方法进行改进:文献方法用氢氧化钠与3,5-二甲基-4-羟基苯甲酸反应制得3,5-二甲基-4-羟基苯甲酸钠,再用3,5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3,5-二甲基-4-羟基苯甲酸苄酯,我们用氢氧化钾代替氢氧化钠,使合成取得成功;在合成2',6'-二甲基-4'-苯基-吖啶-9-甲酸酯时,文献方法对粗产品进行两次硅胶柱层析纯化,第一次柱层析用氯仿/乙酸乙酯(4∶1,V∶V)作溶剂和淋洗剂,第二次柱层析用己烷/丙酮(2∶1,V∶V)作溶剂和淋洗剂,按照文献方法得到的不是所需要的化合物,我们只进行第一次柱层析纯化,然后用己烷/丙酮(2∶1,V∶V)进行研磨,过滤,洗涤,除去溶于己烷/丙酮(2∶1,V∶V)的部分,得到所需要的产品。
