Synthesis of Artificial Antigen of Chloramphicol and Preparation of Polyclonal Antibody
摘要
Abstract
Artificial antigen of chloramphenicol was synthesized by diazotization method. The artificial antigen were identified by UV spectrophotometer, SDS-PAGE electrophoresis and MALDI-TOFMS. Rabbits were immunized with that artificial antigens. The polyantiserum was obtained, and the antiserum titre was determined by ELSIA. The condition of ELISA was optimized. Four antibiotics were chosed to calculate the cross reactivity because of their smilar structure. The result showed conjugation ratio was 22:1 and working concentration of coating antigen was 0.25 μg/mL. The standard curve was eatablished and the value of IC50 was 0.26 μg/mL. Antiserum titre reached 128 000. The cross reactivity of 4 drugs and antibody were less than 0.1% with high specificity.关键词
