摘要： 目的采用免疫竞争法原理,建立一种简便快速检测丁丙诺啡的方法。方法将20nm胶体金颗粒标记的抗丁丙诺啡单克隆抗体,均匀浸在吸水玻璃纤维上,将丁丙诺啡-BSA和纯化后的羊抗鼠IgG多克隆抗体在硝酸纤维薄膜分别划1mm宽的检测线(T线)和质控线(C线),制成丁丙诺啡胶体金标记单克隆抗体免疫层析检测条,并组装成检测板。结果以GC/MS为标准对照,100例样品检测结果显示,本检测板的准确率为99.0%。丁丙诺啡胶体金标记单克隆抗体免疫层析检测板在对45种药(毒)物的测试中,仅识别丁丙诺啡及其主要代谢产物。结论丁丙诺啡胶体金标记单克隆抗体免疫层析检测板在5min内可检出样品中的丁丙诺啡及其代谢物,检测丁丙诺啡的阈值为100ng/mL。

Abstract: Objective To develope an easy to use, rapid and accurate test for detecting buprenorphine based on the principle of competitive immunoassay. Methods Monoclonal antibody against buprenorphine was conjugated with colloidal gold and dispensed on the glass fiber. The complete antigen Buprenorphine-BSA and the goat anti-mouse IgG polyclonal antibody were separately sprayed on the nitrocellulose membrane as the test line (T line) and the control line(C line). The rapid test kit was the final assembled product of test strip with the plastic cover. Results A total of 100 urine samples were tested for buprenorphine by immunochromatographic and GC/MS methods. the accuracy was 99.0%. It is found the test kit can only detect by cross reaction with other 45 kind drugs. Conclusion Rapid test kit can detect buprenorphine in the samples in 5 minutes. The cut-off value of the test is 100 ng/mL.
