According to the result, we believed that the reason resulted in the low sensitivity was that the marker residue compound MQCA structure has changed after conjugated with protein and the antibody induced by the conjugation could not recognize the free MQCA in the ci-ELISA. Therefore we designed some hapten which could reserve the marker residue structural speciality mostly. After synthesis route selection and optimum, the hapten 7-Hydroxymethyl-3-methyl-quinoxaline-2-carboxylic acid was synthesized, used 4-methyl-2-nitroaniline as the start material via six steps, such as oxidation cyclization, bromize reaction, hydrolysis, Beirut reaction, reduction, hydrolysis. This work established basis for producing the high affinity antibody and developing the sensitive ELISA residue detection method.
