摘　　要：为实现克伦特罗残留的规模检测设计其残留检测的免疫芯片。以玻片为载体并对玻片表面进行APTES-DGA化学修饰，将克伦特罗抗体偶联至玻片表面，以牛血清白蛋白封闭玻片表面活性基团，加待测品和标样，标样中辣根过氧化酶标记的克伦特罗和待测品中的克伦特罗与克伦特罗抗体竞争性结合，借助辣根过氧化酶催化化学发光反应并检测光信号值，检测过程中考查加样体积、温育温度、温育时间、洗液浓度及化学发光积分时间等对检测结果的影响，检测方法学试验中考查检出限、定量限、线性和回收率等指标。结果显示：通过APTES。DGA修饰载玻片具有较好的信号均一性和抗体偶联能力，检测过程中加样体积为50μL、温育温度为37℃、温育时间为30min、洗液浓度为10倍稀释液、化学发光积分时间为60s具有较稳定的检测结果。本法研制的免疫芯片检测克伦特罗残留快速、简单、准确。Immunochip is designed in order to realize the massive detection of clenbuterol residue. Slide glass surface as the carrier is modified by APTES-DGA. The clenbuterol antibody is coupled to the slide glass surface. Glass surface active groups are blocked by bovine serum albumin. The samples and standards, horseradish peroxidase labeled clenbuterol are added into the immunochip. CLB and CLB-HRP are combined competitively with Ab （ CLB ）. Chemiluminescence reaction is catalyzed by the horseradish peroxidase and optical signal value is detected. Sampling volume, incubation temperature, incubation time, concentration of washing solution, chemiluminescence integral time are tested. The results show that glass slide with APTES-DGA has a better signal uniformity and antibody coupling ability. In the detection process, immunoehip signal is stable when sampling volume is 50 μL, incubation temperature is 37 ℃, incubation time is 30 min, wash solution concentration is 10 fold diluent and chemiluminescence reader integral time is 60 s. The method is fast, simple and accurate by immunochip analysis for clenbuterol residue.
