| 摘 要： | 建立了一种基于表面等离子体共振(SPR)技术测定畜禽肉中泰乐菌素残留的新方法.用传感芯片(Sensor chips CM5),以25%ACN-0.25 moL/L NaOH为再生溶液,HBS-EP为缓冲溶液,流速为40 μL/min,运用表面等离子体共振(SPR)技术测定畜禽肉中泰乐菌素的含量,结果表明泰乐菌素在32 ng/mL范围内,在Sensor chips CM5表面所产生的相对共振强度与质量浓度有良好的响应关系,平均回收率为80.0%～99.5%,RSD为2.0%～4.7%,检出限为0.03 ng/mL.该方法简便、灵敏,可以为产品的安全与质量控制提供快速分析方法.

| Abstract: | A new method for the determination of rudimental tylosin in livestock meat poultry was established based on surface plasmon resonance(SPR).Under the optimal conditions,the SPR response had a linear relationship with the concentration of tylosin in the range of 1 ng/mL to 32 ng/mL with a detection limit of 0.03 ng/mL.The average recoveries ranged from 80.0% to 99.5% with the RSD from 2.0% to 4.7%.The method is convenient and sensitive,and can be applied for the quality and safety control of food. |
