Abstract: In this paper, artificial haptene was synthesized taking succinic anhydride as spacer arm. Thin-Layer chromatographyand high performance liquid chromatography were applied to determinate it. Then, Reactive Ester Method was used tosynthesis complete antigen. After the level of protein measured with Bradford Method, conjμgated ratio was estimatedassociated with ultraviolet spectroscopy. The results indicated that the purity of hapene was high with the determination ofultraviolet spectroscopy and the conjugated ratio of BSA and OVA were l5 and 4 respectively.
