摘要
以对醛基苯甲酸和N,N-二甲基苯胺为原料,合成了羧化无色孔雀石绿和羧化孔雀石绿;通过薄层色谱分离纯化了合成产物,对各组分进行了高效液相色谱-质谱鉴定,结果表明m/z为375.2和373.2的碎片峰分别为羧化无色孔雀石绿的[M+H]+和羧化孔雀石绿的[M]+准离子峰;将合成的羧化半抗原通过碳化二亚胺与阳离子化BSA偶联,制备完全抗原,经紫外-可见光谱分析计算,两种完全抗原中的羧化无色孔雀石绿和羧化孔雀石绿与BSA的摩尔比分别为9.2∶1和11.1∶1。完全抗原的成功构建为后续抗体制备奠定了物质基础。
In this paper, 4-formylbenzoic acid and N, N-dimethylaniline were used to synthesize carboxyleucomalachite green (CLMG) and carboxymalachite green (CMG). The products were separated and purified by thin layer chromatography, and identified by high performance liquid chromatography-mass spectrum. The results showed that m / z 375.2 and m / z 373.2 were attributed to CLMG (M+H)+ and CMG (M)+ respectively. The complete antigens were prepared by conjugating carboxyhaptens on cationized BSA (cBSA) with EDC and analyzed by ultraviolet-visible spectrum. The molar ratios of two kinds of complete antigens (CLMG-cBSA and CMG-cBSA) were 9.2∶1 and 11.1∶1 respectively. The successful preparation of complete antigens was the foundation for further producing antibodies against leucomalachite green and malachite green.
